The three L-1 0-8-8-0 steam locomotives of the Erie Railroad, built in 1907 by ALCO, were unique in that they were the only articulated camelback locomotives ever built. They were, when built, the largest steam locomotives in existence. They were built for pushing service, especially on the heavy grades of the Delaware and Susquehanna Divisions over the Allegheny Mountains. In 1921 they were rebuilt as 2-8-8-2s with more conventionally located cabs. They were taken out of service in 1930 as larger locomotives replaced them.
