Exhibit 99.1

Email Communication To Employees

I am very pleased to announce an historic acquisition for L.B. Foster. This morning we announced that we have signed an Agreement and Plan of Merger with Portec Rail Products, Inc. Like us, Portec is a Pittsburgh based company that has been in operation for over 100 years.

As you are aware, one of our Rail Group Strategic Initiatives is to become a premier provider of products and services below the wheel for the Class I, transit, shortline and regional railroad and contractors in North America, as well as to governmental agencies and rail contractors globally. This exciting acquisition will allow us to accomplish the following three initiatives:

First, it will broaden our product and service offerings. Portec is a global leader in Friction Management and Wayside Detection.

Second, this acquisition will expand our global reach. Currently, Portec has a strong presence in Canada, the UK and Australia, and has an ever increasing presence in Asia.

Finally, acquiring Portec will allow us to augment our human capital. It is crucial in this competitive environment that we continue to bring the best and brightest into our organization. Further, we believe that this acquisition will provide a multitude of growth opportunities for many L.B. Foster employees.

As we move ahead with this acquisition, I will provide regular communication updates until the transaction closes.

If you have any questions or if you receive questions from any outside party, such as customers, suppliers etc., please refer them to David Sauder, Vice President, Global Business Development, 412-928-3549, or dsauder@lbfosterco.com. All Investor Relations questions should continue to be forwarded to David Russo, Chief Financial Officer, at 412-928-3417, or investors@LBFosterCo.com.

such as interest rate and currency exchange rate fluctuations; technological advances and patents attained by competitors; and domestic and foreign governmental laws and regulations. L. B. Foster can give no assurance that any of the transactions related to the tender offer will be completed or that the conditions to the tender offer and the merger will be satisfied.
