Tee Rail and Crane Rail are available in both new and relay quality. A note about Relay Rail: Relay Rail is rail that has been previously used and then removed due to abandonment of lines or replacement for heavier rail. NARP inspects the relay rail, removes defective rail, reconditions, and then grades it for wear. Feel free to contact one of our sales managers to find the right rail for your railway project.
