"""CSL 3216 is signed for 51st and Central Park. M. E. writes: """"Given that the destination sign reads """"51 - Central Park"""", then this picture was taken from the northwest corner of 51st and Cottage Grove Ave., looking south. The 51st St. line's eastern terminal was actually at 55th St. and the Illinois Central railroad at Lake Park Ave. From there, the route headed west on 55th to Cottage Grove Ave., north to 51st St., and west on 51st St. So the car in this picture is making the turn from northbound Cottage Grove to westbound 51st."""" On the other hand, Graham Garfield writes, """"Note the sign on the light pole that says """"4A"""". Illinois route 4A was a state highway from Joliet to downtown Chicago via Archer Ave. until 1967. Based on buildings in the background that are still extant, the angled street here is Archer and the car is deadheading from Archer carbarn (where the #51 was out of) to 51st St to start its run. We are looking northeast at Archer/Kedzie."""""""
