Following up on an earlier post ... There were line phones at Mesta St. stop, Bethel Park. Evidence is a picture taken by Art Ellis showing 1) the station name and 2) a white hat talking on the telphone. Photo is undated but it shows clean car 1159, a TDH 3207 GM diesel bus, and a 1942 Chevrolet. That sort of places it after WW2 but before 1950.
