Until April 25, 1975, Route 36 trolleys would continue west along what was called Eastwick Avenue out to 88th Street, where a single counterclockwise loop built in the swamplands.

Prior to that point the western terminus of the Route 36 trolley was moved around to several locations in southwestern Philadelphia.

In 1985, Island Avenue was converted into a new bridge over the SEPTA Airport Line near the station, and the intersection of 80th Street and Eastwick Avenue was replaced by a frontage road loop on the north side of the tracks.

[2] Today's current trolley loop is located on the northwest corner of this bridge.

Some of the former termini of the line are now located within the John Heinz National Wildlife Refuge at Tinicum.
