The FGLK operates a portion of the ex-Lehigh Valley Railroad mainline from Geneva to Kendaia running south on the east side of Seneca Lake. This was the Lehigh Valley's mainline from Waverly, New York to Buffalo, New York. This line saw much action during World War II and the Cold War with many military movements in and out of the Seneca Army Depot until it closed in the summer 1998. The now-closed base has a very large yard which at current time is used for rail car storage by the Finger Lakes Railway. The local industrial development agency works to attract new industries to locate at the abandoned depot because of the rail infrastructure.
