The Blue Line is also one of only two lines with more than one station with the same name, with the Green Line being the other (It has two stations at Harlem Avenue: one in the Kennedy Expressway on the Northwest side and one on the south side of the Eisenhower Expressway in Forest Park, Illinois. It also has two stations on Western Avenue: one on the O'Hare branch and one on the Congress branch). The Blue Line also has only three in-system transfers (all in the Loop), contains a combination of both the oldest and newest portions of 'L' tracks, and does not share tracks with any other 'L' line.
