I recently bought a 1961 Philadelphia Division ETT, and there's a pair of trains that I can't figure out. Both were daily ex. Sat/Sun/holidays. It was a non-passenger-carrying run both ways, and covered just under a mile in each direction. Train 831 left Newtown 6:10am and arrived George School 6:15. Then it would "spin" and become 832, lv George School 6:38 and ar Newtown 6:43. It's gone by my next ETT from 1963. Anyone have any idea what this run could have been for? I thought perhaps a literal "milk run" to collect milk to put on the first passenger train out. There was a freight house at George School, but why not just bring the milk right to Newtown? Another thought was that it was to polish up the rails for an adequate shunt for crossing protection at State St., but that's also just a guess. Anybody have other ideas or know what this "dinky" did?
