In the 1800s, T-Rail was formed by squeezing billets of hot iron between heavy cast-iron rollers. Multiple passes altered the profile until the desired shape was attained. Lackawanna Iron both purchased and produced its own rolls, and other heavy parts, at its foundry and machine shop. In late 1847 the company received an award for producing the best specimen of T-rail in the nation.
