L.B. Foster Transit Products has both fiberglass and porcelain insulators for all types of transit and railroad applications. Contact us for any of your insulator installations, whether it be top running, under running or side running contact rail system. 

We can offer either stock insulators or develop one specific to your application. Customers include virtually all North American heavy rail transit systems.

Coverboard / Protection Board

L.B. Foster's Transit Products division has developed coverboard systems that provide maximum protection for personnel and the power rail at economical prices. These systems have been installed across North America. Each one has been specifically designed to meet the transit agency's special criteria and to perform effectively under local climate conditions such as wind, snow and ice. 

The coverboards are made predominately of a strong, lightweight fiberglass composite which provides high levels of electrical insulation and includes low-smoke, flame-resistant materials. They are easily installed on new or existing systems. 

You can see the L.B. Foster Transit Product's coverboard systems in service in many U.S. transit systems- among them Washington's WMATA, Baltimore's MTA, Atlanta's MARTA, SEPTA, New York City Transit, Amtrak, San Francisco's BART, and Los Angeles' MTA. 

Let us show you one of our existing coverboard systems, or design a new one to meet your special needs. Discover the difference L.B. Foster contact rail coverboard systems can make in your transit operation. 

Coverboard Brackets

We have coverboard bracket systems that are made from electrical isolating fiberglass material that is proven to withstand a hostile environment.  This material and the design of the brackets are such that they will hold the coverboards in place under heavy static and impact loads.  The material also electrically isolates the contact power rail from ground.  We have brackets for under running, over running and side running contact power rail systems that will work with all types of contact rail.

In addition to the fiberglass bracket systems, we have steel brackets that attach to wood ties, concrete ties and other structures.


Third Rail Appurtenances

As part of the various contact rail systems that L.B. Foster Company can provide, we offer end approaches (ramps/inclines), side approaches, expansion joints, contact rail anchor assemblies, concrete or wood tie extension channels and concrete insert systems designed and proven to work.  Let us provide you with our complete contact rail system or design one to meet your specific needs.
