The CTA has a yard for the Green Line (formerly the Lake Street “L”) just west of the Harlem Avenue terminal in suburban Forest Park. Here, various cars in the 2000-series are seen, along with a Metra commuter train on the adjacent Union Pacific West Line. This picture was most likely taken during the 1990s. (Bruce C.
