former NYC RR's JF&C Branch and the former Erie RR's Chicago—New York main line at Osgood. It then passes east of downtown Greenville at a relatively high elevation, and rejoins the original line at KY, near Kremis. The K-O Line cut-off shortened KO to KY run by 3.1 miles vs. the Old Line. Except for the Osgood Viaduct, this cut-off was double-tracked for many years but, since the arrival of CTC signaling in the 1950s, is now entirely single track. The B&LE operated a line from Queen Junction (near Butler, Pennsylvania) to Brady's Bend, Pennsylvania. It was known as the Western Allegheny Division, and was notable for being the last line that the B&LE's F-Units ran on. F-unit service on the line ended in 1992, and the last train, which was pulled by an EMD SD9 ran in November 1994. The line sat out of service until 2000, when it was abandoned. The tracks were removed in 2002, and today, the right of way is barely visible. There was originally one tunnel on the B&LE mainline at Culmerville, but it was dug out or "daylighted" in 1922, converting it to an open cut through a hill. As it approaches North Bessemer, the B&LE is also noticeable where it crosses the Allegheny River on the Bessemer & Lake Erie Railroad Bridge immediately east of and parallel to the Pennsylvania Turnpike. Locomotives In the steam era, B&LE had a fleet of 2-8-0 "Consolidation" types, classes C1 through C4; 2-10-2 "Santa Fe" types, classes D1 and D2; and 2-10-4 "Texas" type locomotives, class H1. The H1 locomotives were one of the most powerful non-articulated locomotives ever constructed. The B&LE also had a number of switchers, including 0-6-0s and 0-8-0s. Two steam locomotives from the B&LE have been preserved, which are 2-10-4 No. 643 and 2-8-0 No. 154. The road was dieselized in 1953. In the diesel era, B&LE's motive power has always been mostly Electro-Motive Division. It dieselized with many EMD F-units, which were supplemented by SD9s, SD18s, and ALCo RSD15s. Later, it bought a number of EMD SD38ACs and SD38-2s to replace the F-units. In the late 1990s, it bought many EMD SD40T-3 "Tunnel Motors" from Southern Pacific Railroad to replace the 1950s-vintage SD9s. As a subsidiary of CN, the B&LE has been largely unchanged (though repainting of B&LE locomotives into CN paint with "BLE" sub-lettering began in April 2015). Bessemer and
