37th Street/Spruce Street/Woodland Avenue is a SEPTA Subway-Surface Lines trolley station. It is the last station in the tunnel before the 40th Street Subway Portal and carries Subway-Surface Trolley Routes 11, 13, 34, & 36. The entrance to go down into the eastbound side of the station is on the campus of the University of Pennsylvania and the entrance to go down into the westbound side of the station is on Spruce Street. The two stations are off set and are not on the same length of the track. Trolleys serving this station go eastbound to Center City Philadelphia and Westbound to the Philadelphia neighborhoods of Eastwick and Angora and the Delaware County suburbs of Yeadon and Darby. The reason why the station platforms are off set is because during construction of the subway station the above intersection was Spruce & 37th Streets at Woodland Avenue with all three streets crossing at a five points intersection.
