Financial Statements [Abstract]
FINANCIAL STATEMENTS	1. FINANCIAL STATEMENTS The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all estimates and adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. However, actual results could differ from those estimates. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. Amounts included in the balance sheet as of December 31, 2011 were derived from our audited balance sheet. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2011. Certain accounts in the prior year period condensed consolidated financial statements have been reclassified for comparative purposes principally to conform to the presentation of discontinued operations in the current year period.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

INVESTMENTS

6. INVESTMENTS

Investments of the Company consist of a nonconsolidated equity method investment of $4,137,000 and $3,495,000 at September 30, 2012 and December 31, 2011, respectively.

The Company is a member of a joint venture with L B Industries, Inc. and James Legg until September 30, 2019. The Company and L B Industries, Inc. each have a 45% ownership interest in the joint venture, L B Pipe & Coupling Products, LLC (JV). The JV manufactures, markets and sells various products for the energy, utility and construction markets. Under the terms of the JV agreement, as amended, the Company was required to make capital contributions totaling approximately $3,000,000. The Company fulfilled these commitments during 2011. The other JV members are required to make proportionate contributions in accordance with the ownership percentages in the JV agreement.

Under applicable guidance for variable interest entities in ASC 810, “Consolidation,” the Company determined that the JV is a variable interest entity, as the JV has not demonstrated that it has sufficient equity to support its operations without additional financial support. The Company concluded that it is not the primary beneficiary of the variable interest entity, as the Company does not have a controlling financial interest and does not have the power to direct the activities that most significantly impact the economic performance of the JV. Accordingly, the Company concluded that the equity method of accounting remains appropriate.

The Company recorded equity in the income of the JV of approximately $310,000 and $643,000 for the three and nine months ended September 30, 2012, respectively. The Company recorded equity in the income of the JV of approximately $287,000 and $570,000 for the three and nine months ended September 30, 2011, respectively.

The Company’s exposure to loss results from its capital contributions, net of the Company’s share of the JV’s income or loss, and its net investment in the direct financing lease covering the facility used by the JV for its operations. The carrying amounts with the maximum exposure to loss of the Company at September 30, 2012 and December 31, 2011, respectively, are as follows:



		September 30,		December 31,
		2012		2011
		In thousands
Equity method investment	$	4,137	$	3,495
Net investment in direct financing lease		933		971

Borrowings [Abstract]
BORROWINGS	8. BORROWINGS United States On May 2, 2011, the Company, its domestic subsidiaries, and certain of its Canadian subsidiaries entered into a new $125,000,000 Revolving Credit Facility Credit Agreement (Credit Agreement) with PNC Bank, N.A., Bank of America, N.A., Wells Fargo Bank, N.A. and Citizens Bank of Pennsylvania. This Credit Agreement replaced a prior revolving credit facility with a maximum credit line of $90,000,000 and a $20,000,000 term loan. The Credit Agreement provides for a five-year, unsecured revolving credit facility that permits borrowing up to $125,000,000 for the U.S. borrowers and a sublimit of the equivalent of $15,000,000 U.S. dollars that is available to the Canadian borrowers. Provided no event of default exists, the Credit Agreement contains a provision that provides for an increase in the revolver facility of $50,000,000 that can be allocated to existing or new lenders if the Company’s borrowing requirements should increase. The Credit Agreement includes a sublimit of $20,000,000 for the issuance of trade and standby letters of credit. Borrowings under the Credit Agreement will bear interest at rates based upon either the base rate or LIBOR-based rate plus applicable margins. Applicable margins are dictated by the ratio of the Company’s indebtedness less cash on hand to the Company’s consolidated EBITDA, as defined in the underlying Credit Agreement. The base rate is the highest of (a) PNC Bank’s prime rate, (b) the Federal Funds Rate plus 0.50% or (c) the daily LIBOR rate, as defined in the underlying Credit Agreement, plus 1.00%. The base rate spread ranges from 0.00% to 1.00%. LIBOR-based rates are determined by dividing the published LIBOR rate by a number equal to 1.00 minus the percentage prescribed by the Federal Reserve for determining the maximum reserve requirements with respect to any Eurocurrency funding by banks on such day. The LIBOR-based rate spread ranges from 1.00% to 2.00%. The Credit Agreement includes two financial covenants: (a) the Leverage Ratio, defined as the Company’s Indebtedness less cash on hand divided by the Company’s consolidated EBITDA, which must not exceed 3.00 to 1.00 and (b) Minimum Interest Coverage, defined as consolidated EBITDA less Capital Expenditures divided by consolidated interest expense, which must be no less than 3.00 to 1.00. The Credit Agreement permits the Company to pay dividends and distributions and make redemptions with respect to its stock provided no event of default or potential default (as defined in the Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Dividends, distributions, and redemptions are capped at $15,000,000 per year when funds are drawn on the facility. If no drawings on the facility exist, dividends, distributions, and redemptions in excess of $15,000,000 per year are subjected to a limitation of $75,000,000 in aggregate. The $75,000,000 aggregate limitation also includes certain loans, investments, and acquisitions. The Company is permitted to acquire the stock or assets of other entities with limited restrictions provided that the Leverage Ratio does not exceed 2.50 to 1.00 after giving effect to the acquisition. Other restrictions exist at all times including, but not limited to, limitation of the Company’s sale of assets, other indebtedness incurred by either the borrowers or the non-borrower subsidiaries of the Company, guaranties, and liens. On July 9, 2012, the Company amended the Credit Agreement to increase the limitation of the Company’s sale of assets from $10,000,000 to $25,000,000. As of September 30, 2012, the Company was in compliance with the Credit Agreement’s covenants. The Company had no outstanding borrowings under the revolving credit facility at September 30, 2012 or December 31, 2011 and had available borrowing capacity of $123,824,000 at September 30, 2012. Letters of Credit At September 30, 2012, the Company had outstanding letters of credit of approximately $1,176,000. United Kingdom A subsidiary of the Company has a working capital facility with NatWest Bank for its United Kingdom operations which includes an overdraft availability of £1,500,000 pounds sterling (approximately $2,424,000 at September 30, 2012). This credit facility supports the subsidiary’s working capital requirements and is collateralized by substantially all of the assets of its United Kingdom operations. The interest rate on this facility is the financial institution’s base rate plus 1.50%. Outstanding performance bonds reduce availability under this credit facility. The subsidiary of the Company had no outstanding borrowings under this credit facility as of September 30, 2012. There was approximately $61,000 in outstanding guarantees (as defined in the underlying agreement) at September 30, 2012. There were no borrowings or performance bonds outstanding on this facility as of December 31, 2011. This credit facility was renewed effective August 30, 2012 with no significant changes to the underlying terms or conditions in the facility. The expiration date of this credit facility is August 30, 2013. The United Kingdom loan agreements contain certain financial covenants that require that subsidiary to maintain senior interest and cash flow coverage ratios. The subsidiary was in compliance with these financial covenants as of September 30, 2012. The subsidiary had available borrowing capacity of $2,363,000 at September 30, 2012.

On August 30, 2012, the Company sold substantially all of the assets and liabilities of its precise structural products business, Precise, for $2,643,000 to Cianbro Fabrication and Coating Corporation, resulting in a pre-tax loss of approximately $315,000.

The operations of these divisions qualify as a “component of an entity” under FASB ASC 205-20, “Presentation of Financial Statements – Discontinued Operations” and thus, the operations have been reclassified as discontinued and prior periods have been reclassified to conform to this presentation. Future expenses of discontinued operations are not expected to be material.

Net sales and income, including the pre-tax gain of $3,193,000, from discontinued operations were as follows:

Stock-Based Compensation [Abstract]

SHARE-BASED COMPENSATION

11. SHARE-BASED COMPENSATION

The Company applies the provisions of FASB ASC 718, “Compensation – Stock Compensation,” to account for the Company’s share-based compensation. Share-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized over the employees’ requisite service period. The Company recorded stock compensation expense of $477,000 and $465,000 for the three-month periods ended September 30, 2012 and 2011, respectively, and $1,312,000 and $1,720,000 for the nine-month periods ended September 30, 2012 and 2011, respectively, related to restricted stock awards and performance unit awards.

Stock Option Awards

A summary of the option activity as of September 30, 2012 is presented below.



				Weighted
			Weighted	Average
			Average	Remaining		Aggregate
			Exercise	Contractual		Intrinsic
	Shares		Price	Term		Value
Outstanding and Exercisable at January 1, 2012	39,950	$	8.94	2.8

The total intrinsic value of options outstanding and exercisable at September 30, 2011 was $669,000.

At September 30, 2012, common stock options outstanding and exercisable under the Company’s equity plans had option prices ranging from $4.10 to $14.77, with a weighted average exercise price of $9.94. At September 30, 2011, common stock options outstanding and exercisable under the Company’s equity plans had option prices ranging from $4.10 to $14.77, with a weighted average exercise price of $8.83 per share.

The weighted average remaining contractual life of the stock options outstanding at September 30, 2012 and 2011 was 2.4 and 3.1 years, respectively.

There were 10,000 options with a weighted average exercise price per share of $6.02 exercised during the three-month period ended September 30, 2012. There were 10,000 options with a weighted average exercise price per share of $4.87 exercised during the three-month period ended September 30, 2011. The total intrinsic value of options exercised during the three-month periods ended September 30, 2012 and 2011 was $225,000 and $154,000, respectively.

Options exercised during the nine-month periods ended September 30, 2012 and 2011 totaled 11,450 and 31,000 shares, respectively. The weighted average exercise price per share of the options exercised during the nine-month periods ended September 30, 2012 and 2011 were $6.44 and $3.93, respectively. The total intrinsic value of options exercised during the nine-month periods ended September 30, 2012 and 2011 were $255,000 and $909,000, respectively.

Restricted Stock Awards

For the nine-month periods ended September 30, 2012 and 2011, the Company granted approximately 26,000 and 46,000 shares, respectively, of restricted stock to employees. During the nine-month period ended September 30, 2012, the Company also granted approximately 66,000 shares of restricted stock to an employee director. A summary of restricted stock award activity follows:



					Aggregate
			Grant Date		Fair
Grant Date	Shares		Fair Value		Value	Vesting Date
March 15, 2011	24,836	$	38.46	$	955,000	March 15, 2015
July 21, 2011	16,600		38.44		638,000	July 21, 2015
August 29, 2011	5,000		24.50		123,000	August 29, 2014

May 23, 2012	8,000		28.05		224,000	May 23, 2016

These forfeitable Restricted Stock Awards time-vest after a four-year holding period, unless indicated otherwise by the underlying Restricted Stock Agreement. Certain awards of restricted stock included in the above table provide for partial vesting over a period up to the vesting date listed. Shares issued as a result of Restricted Stock Awards generally are previously issued shares which have been reacquired by the Company and held as Treasury shares or authorized but previously unissued common stock.

Performance Unit Awards

Annually, under separate three-year long-term incentive plans, pursuant to the Omnibus Plan, the Company grants performance units. Units granted during the nine-month periods ended September 30 are as follows:



						Aggregate
Incentive				Grant Date		Fair
Plan	Grant Date	Units		Fair Value		Value	Vesting Date
2010 - 2012	March 2, 2010	36,541	$	31.83	$	1,163,000	March 2, 2013
2011 - 2013	March 15, 2011	34,002		38.46		1,308,000	March 15, 2014
2012 - 2014	March 6, 2012	43,042		27.49		1,183,000	March 6, 2015

In addition, on March 15, 2011 the Company awarded, pursuant to the Omnibus Plan, 1,500 special performance units to an employee director and 1,000 special performance units to an executive officer. Based on the satisfaction of the underlying performance conditions, these units were converted, net of shares withheld for applicable income tax purposes, into 1,436 and 957 shares, respectively, of the Company’s common stock on March 6, 2012. The grant date fair value of these awards was $38.46 and the aggregate fair value was $58,000 and $38,000, respectively.

Performance units are subject to forfeiture and will be converted into common stock of the Company based upon the Company’s performance relative to performance measures and conversion multiples as defined in the underlying plan. The aggregate fair value in the above table is based upon achieving 100% of the performance targets as defined in the underlying plan. The Company reversed $1,157,000 of incentive compensation expense during the nine-month period ended September 30, 2012 caused by the impact of the product warranty charge on Company performance, as it related to the awards’ underlying performance conditions. More information on the product warranty charge can be found in Note 14.

Shares issued as a result of performance unit awards generally are previously issued shares which have been reacquired by the Company and held as Treasury shares or authorized but previously unissued common stock.

The excess tax benefit realized for the tax deduction from stock-based compensation approximated $121,000 and $368,000 for the nine months ended September 30, 2012 and 2011, respectively. This excess tax benefit is included in cash flows from financing activities in the Condensed Consolidated Statements of Cash Flows.

Defined Contribution Plans

The Company has a domestic defined contribution plan that covers all non-union hourly and all salaried employees (Salaried Plan). The Salaried Plan permits both pre-tax and after-tax employee contributions. Participants can contribute, subject to statutory limitations, between 1% and 75% of eligible pre-tax pay and between 1% and 100% of eligible after-tax pay. The Company's employer match is 100% of the first 1% of deferred eligible compensation and up to 50% of the next 6%, based on years of service, of deferred eligible compensation, for a total maximum potential match of 4%. The Company may also make discretionary contributions to the Salaried Plan.

The Company also has a domestic defined contribution plan for union hourly employees with contributions made by both the participants and the Company based on various formulas (Union Plan).

The Company’s Portec Rail subsidiary maintains a defined contribution plan covering all non-union employees at its Montreal, Quebec, Canada location (Montreal Plan).

Fair Value Measurements

9 Months Ended

Fair Value Measurements [Abstract]

FAIR VALUE MEASUREMENTS

13. FAIR VALUE MEASUREMENTS

FASB ASC 820, “Fair Value Measurements and Disclosures,” defines fair value, establishes a framework for measuring fair value in accordance with accounting principles generally accepted in the United States, and expands disclosures about fair value measurements. The Company applies the provisions of ASC 820 to all its assets and liabilities that are being measured and reported on a fair value basis.

ASC 820 discusses valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). ASC 820 enables readers of financial statements to assess the inputs used to develop those measurements by establishing a hierarchy, which prioritizes those inputs used, for ranking the quality and reliability of the information used to determine fair values. The standard requires that each asset and liability carried at fair value be classified into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that are not corroborated by market data.

The Company has an established process for determining fair value for its financial assets and liabilities, principally cash and cash equivalents and foreign currency exchange contracts. Fair value is based on quoted market prices, where available. If quoted market prices are not available, fair value is based on assumptions that use as inputs market-based parameters. The following sections describe the valuation methodologies used by the Company to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate the description includes details of the key inputs to the valuations and any significant assumptions.

Cash equivalents. Included within “Cash and cash equivalents” are investments in tax-free and taxable money market funds with municipal bond issuances as the underlying securities as well as government agency obligations and corporate bonds, all of which maintain AAA credit ratings. Also included within cash equivalents are our investments in non-domestic bank certificates of deposit. The Company uses quoted market prices to determine the fair value of these investments and they are classified in Level 1 of the fair value hierarchy. The carrying amounts approximate fair value because of the short maturity of the instruments.

Derivative contracts. The Company uses significant other observable inputs that are readily available in public markets or can be derived from information available in publicly quoted markets to determine the fair value of its derivative contracts. These instruments consist of foreign currency exchange contracts, are included within “Other accrued liabilities,” and are classified in Level 2 of the fair value hierarchy. Fluctuations in the fair values of derivative instruments are recorded in accumulated other comprehensive loss and reclassified into earnings as the underlying hedged items affect earnings. There were no such instruments as of December 31, 2011.

IDSI acquisition notes. The Company issued non-interest bearing notes associated with its 2010 acquisition of Interlocking Deck Systems International, LLC (IDSI). The Company determined the fair value of these notes by computing the present value of the note payments using an interest rate formula applicable to the Company’s long-term debt. This note was paid during the three-month period ended March 31, 2012. The note was included within “Current maturities of long-term debt” at December 31, 2011.

The following assets and liabilities of the Company were measured at fair value on a recurring basis subject to the disclosure requirements of ASC Topic 820 at September 30, 2012 and December 31, 2011:

Commitments and Contingent Liabilities [Abstract]

COMMITMENTS AND CONTINGENT LIABILITIES

14. COMMITMENTS AND CONTINGENT LIABILITIES

Product Liability Claims

On July 12, 2011, the Union Pacific Railroad (UPRR) notified (the “UPRR Notice”) the Company and the Company’s subsidiary, CXT Incorporated (CXT), of a warranty claim under CXT's 2005 supply contract relating to the sale of prestressed concrete railroad ties to the UPRR. The UPRR asserted that a significant percentage of concrete ties manufactured in 2006 through 2011 at CXT's Grand Island, NE facility fail to meet contract specifications, have workmanship defects and are cracking and failing prematurely. Approximately 1.6 million ties were sold from Grand Island to the UPRR during the period the UPRR has claimed nonconformance. The 2005 contract calls for each concrete tie which fails to conform to the specifications or has a material defect in workmanship to be replaced with 1.5 new concrete ties, provided, that UPRR within five years of the sale of a concrete tie, notifies CXT of such failure to conform or such defect in workmanship. The UPRR Notice did not specify how many ties manufactured during this period are defective nor the exact nature of the alleged workmanship defect. Additionally, UPRR notified the Company that a customer of the UPRR asserted that a representative sample of ties manufactured by the Company’s Grand Island facility have failed a test contained in the contract specification. UPRR has removed, at this customer’s request, approximately 115,000 concrete ties, which are a subset of the ties subject to the UPRR Notice.

On January 11, 2012, CXT received a subpoena from the United States Department of Transportation Inspector General (IG) requesting records related to its manufacture of concrete railroad ties in Grand Island, Nebraska. The Company believes that this subpoena relates to the same set of circumstances giving rise to the UPRR product claim. CXT and the Company have been cooperating fully with the IG.

November 7, 2012 Update

The Company has been assessing warranty claims for certain concrete ties made in its Grand Island, NE facility. The claims are arising from ties found in track that are not performing up to the Company’s expectations, and do not meet the Company’s quality standards. These ties were manufactured between 1998 and 2011. The Company discontinued manufacturing operations in Grand Island in early 2011. The large majority of these claims come from the Union Pacific Railroad (UPRR). During the recent quarter, the Company has been working to resolve the claims in a satisfactory manner for our customers and the Company. The Company made substantial progress with the UPRR in the recent quarter regarding the approach to remedy field failures, the details of which are in the following paragraphs.

The Company has agreed on a process with the UPRR for identifying, prioritizing and replacing ties that meet the criteria for replacement. This process will be applied to the ties the Company shipped to the UPRR from its Grand Island, NE facility from 1998 to 2011. During most of this period the Company’s warranty policy for UPRR carried a 5 year warranty with a 1.5:1 replacement ratio for any defective ties. The agreed upon process will result in the Company and the UPRR working together to identify and replace defective ties. The process of planning and documenting will be done by both the Company and the UPRR to ensure this is done in a timely manner.

In order to accommodate customer concerns, the Company has reverted to a previously used warranty policy. This will result in all concrete ties with a 5 year warranty and a 1.5:1 replacement ratio, now having a 15 year warranty and a 1:1 replacement ratio. This change will provide an additional 10 years of warranty protection. The 1:1 replacement ratio will furnish one tie for each tie replaced under our claims process.

Following the changes noted above to the warranty policy and our assessment of the scope of the defective ties, the Company recorded an additional $3.0 million warranty charge in order to adequately reserve for the revised cost of resolving expected claims. This change brought the total warranty reserve for concrete ties to $27.2 million. It is now sized to reflect the expected claims from all customers who have notified the Company of problems, especially the UPRR where the majority of claims arose. It is supported by the extensive field sampling and forensic analysis we’ve conducted along with customer discussions.

Finally, the Company will produce the replacement ties in its Tucson, AZ manufacturing facility which has been operating under a 5 year supply contract with the UPRR expiring in December 2012. UPRR has verbally indicated their intent to award the Company with a new 5 year supply contract for its Tucson facility. The details of this supply contract have not been completed, although they are expected to closely resemble the terms in the existing contract with the exception of the new 15 year warranty policy and some product specification changes.

The Company is subject to product warranty claims that arise in the ordinary course of its business. For certain manufactured products, the Company maintains a product warranty accrual which is adjusted on a monthly basis as a percentage of cost of sales. This product warranty accrual is periodically adjusted based on the identification or resolution of known individual product warranty claims. The following table sets forth the Company’s continuing operations product warranty accrual:



		In thousands
Balance at December 31, 2011	$	6,632
Additions to warranty liability		23,993
Warranty liability utilized		(2,512)
Balance at September 30, 2012	$	28,113

While the Company believes this is a reasonable estimate of these potential warranty claims, these estimates could change due to new information and future events. There can be no assurance at this point that future potential costs pertaining to these claims or other potential future claims will not have a material impact on the Company’s results of operations.

Environmental and Legal Proceedings

The Company is subject to national, state, foreign, provincial and/or local laws and regulations relating to the protection of the environment, and the Company is monitoring its potential environmental exposure related to current and former Portec facilities. The Company’s efforts to comply with environmental regulations may have an adverse effect on its future earnings. In the opinion of management, compliance with the present environmental protection laws will not have a material adverse effect on the financial condition, results of operations, cash flows, competitive position or capital expenditures of the Company.

The Company is also subject to legal proceedings and claims that arise in the ordinary course of its business. In the opinion of management, the amount of ultimate liability with respect to these actions will not materially affect the financial condition or liquidity of the Company. The resolution, in any reporting period, of one or more of these matters could have a material effect on the Company’s results of operations for that period.

As of September 30, 2012 and December 31, 2011, the Company maintained environmental and litigation reserves approximating $2,112,000 and $2,184,000, respectively.

Derivative Financial Instruments and Hedging Activities	9 Months Ended
Derivative Financial Instruments and Hedging Activities	Sep. 30, 2012
Derivative Financial Instruments and Hedging Activities [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	15. DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES The Company does not purchase or hold any derivative financial instruments for trading purposes. At contract inception, the Company designates its derivative instruments as hedges. The Company recognizes all derivative instruments on the balance sheet at fair value. Fluctuations in the fair values of derivative instruments designated as cash flow hedges are recorded in accumulated other comprehensive (loss) income and reclassified into earnings within other income as the underlying hedged items affect earnings. To the extent that a change in the derivative does not perfectly offset the change in value of the risk being hedged, the ineffective portion is recognized in earnings immediately. The Company is subject to exposures to changes in foreign currency exchange rates. The Company manages its exposure to changes in foreign currency exchange rates on firm sale and purchase commitments by entering into foreign currency forward contracts. The Company’s risk management objective is to reduce its exposure to the effects of changes in exchange rates on these transactions over the duration of the transactions. During the third quarter of 2012, the Company executed derivative contracts with notional amounts totaling approximately $3,186,000 to sell Canadian funds based on the anticipated receipt of Canadian funds from the sale of certain rail products in the third quarter of 2012. The receipt of Canadian funds did not occur when the Company expected and the Company needed to enter into another commitment to buy Canadian funds with notional amounts totaling approximately $3,388,000. During the third quarter of 2012, the Company settled these contracts for a recognized loss of approximately $204,000. This amount is included within “Other expense/(income)” in the Condensed Consolidated Statements of Operations. During the third quarter of 2012, the Company entered into a new commitment with notional amounts totaling approximately $3,280,000 to sell Canadian funds based on the anticipated receipt of Canadian funds from the sale of certain rail products in the fourth quarter of 2012. The fair value of this instrument was a liability of approximately $47,000 as of September 30, 2012 and was recorded in “Other accrued liabilities” in the Condensed Consolidated Balance Sheet. The Company did not engage in any foreign currency hedging transactions during the nine-month period ended September 30, 2011.

- Definition

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

Inventories (Policies)	9 Months Ended
Inventories (Policies)	Sep. 30, 2012
Inventories [Abstract]
Inventory, Policy [Policy Text Block]	Inventories of the Company’s continuing operations are generally valued at the lower of last-in, first-out (LIFO) cost or market. Other inventories of the Company are valued at average cost or market, whichever is lower. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels and costs at that time. Interim LIFO calculations are based on management’s estimates of expected year-end levels and costs.

- Definition

Disclosure of accounting policy for major classes of inventories, bases of stating inventories (for example, lower of cost or market), methods by which amounts are added and removed from inventory classes (for example, FIFO, LIFO, or average cost), loss recognition on impairment of inventories, and situations in which inventories are stated above cost. If inventory is carried at cost, this disclosure includes the nature of the cost elements included in inventory.

- Definition

Tabular disclosure of the significant judgments and assumptions made in determining whether a variable interest (as defined) held by the entity requires the variable interest entity (VIE) (as defined) to be consolidated and (or) disclose information about its involvement with the VIE, individually or in aggregate (as applicable); the nature of restrictions, if any, on the consolidated VIE's assets and on the settlement of its liabilities reported by an entity in its statement of financial position, including the carrying amounts of such assets and liabilities; the nature of, and changes in, the risks associated with involvement in the VIE; how involvement with the VIE affects the entity's financial position, financial performance, and cash flows; the lack of recourse if creditors (or beneficial interest holders) of the consolidated VIE have no recourse to the general credit of the primary beneficiary (if applicable); the terms of arrangements, giving consideration to both explicit arrangements and implicit variable interests, if any, that could require the entity to provide financial support to the VIE, including events or circumstances that could expose the entity to a loss; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; the significant factors considered and judgments made in determining that the power to direct the activities of a VIE that most significantly impact the VIE's economic performance are shared (as defined); the carrying amounts and classification of assets and liabilities of the VIE included in the statement of financial position; the entity's maximum exposure to loss, if any, as a result of its involvement with the VIE, including how the maximum exposure is determined and significant sources of the entity's exposure to the VIE; a comparison of the carrying amounts of the assets and liabilities and the entity's maximum exposure to loss; information about any liquidity arrangements, guarantees, and (or) other commitments by third parties that may affect the fair value or risk of the entity's variable interest in the VIE; whether or not the entity has provided financial support or other support (explicitly or implicitly) to the VIE that it was not previously contractually required to provide or whether the entity intends to provide that support, including the type and amount of the support and the primary reasons for providing the support; and supplemental information the entity determines necessary to provide.

Line of Credit Facility, Maximum Borrowing Capacity			125,000,000
Line of Credit Facility, Description	This Credit Agreement replaced a prior revolving credit facility with a maximum credit line of $90,000,000 and a $20,000,000 term loan.
Line of Credit Facility, Borrowing Capacity, Description	The Credit Agreement provides for a five-year, unsecured revolving credit facility that permits borrowing up to $125,000,000 for the U.S. borrowers and a sublimit of the equivalent of $15,000,000 U.S. dollars that is available to the Canadian borrowers.
Line of Credit Facility, Interest Rate Description	Borrowings under the Credit Agreement will bear interest at rates based upon either the base rate or LIBOR-based rate plus applicable margins. Applicable margins are dictated by the ratio of the Company's indebtedness less cash on hand to the Company's consolidated EBITDA, as defined in the underlying Credit Agreement. The base rate is the highest of (a) PNC Bank's prime rate, (b) the Federal Funds Rate plus 0.50% or (c) the daily LIBOR rate, as defined in the underlying Credit Agreement, plus 1.00%. The base rate spread ranges from 0.00% to 1.00%. LIBOR-based rates are determined by dividing the published LIBOR rate by a number equal to 1.00 minus the percentage prescribed by the Federal Reserve for determining the maximum reserve requirements with respect to any Eurocurrency funding by banks on such day. The LIBOR-based rate spread ranges from 1.00% to 2.00%.
Line of Credit Facility, Covenant Terms	The Credit Agreement includes two financial covenants: (a) the Leverage Ratio, defined as the Company's Indebtedness less cash on hand divided by the Company's consolidated EBITDA, which must not exceed 3.00 to 1.00 and (b) Minimum Interest Coverage, defined as consolidated EBITDA less Capital Expenditures divided by consolidated interest expense, which must be no less than 3.00 to 1.00.
Line of Credit Facility, Dividend Restrictions	The Credit Agreement permits the Company to pay dividends and distributions and make redemptions with respect to its stock provided no event of default or potential default (as defined in the Credit Agreement) has occurred prior to or after giving effect to the dividend, distribution, or redemption. Dividends, distributions, and redemptions are capped at $15,000,000 per year when funds are drawn on the facility. If no drawings on the facility exist, dividends, distributions, and redemptions in excess of $15,000,000 per year are subjected to a limitation of $75,000,000 in aggregate. The $75,000,000 aggregate limitation also includes certain loans, investments, and acquisitions. The Company is permitted to acquire the stock or assets of other entities with limited restrictions provided that the Leverage Ratio does not exceed 2.50 to 1.00 after giving effect to the acquisition.
