| American Locomotive Company|Erie L-1 Wikipedia
The three L-1 0-8-8-0 steam locomotives of the Erie Railroad, built in July 1907 by ALCO, and numbered 2600, 2601 and 2602; were unique in that they were the only articulated camelback locomotives ever built. When built, they were the largest steam locomotives in the World. The Locomotive itself weighed 410,000 Lbs. (260 Tons) 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 December 1930 as larger locomotives replaced them.
