CF, I'm just a west coast, short line engineer, I've never heard of this "Valley" you keep refering to.......
The mainline of the Valley used to run through Oak Island, over the Upper Bay bridge, and down to Johnson Ave, and Claremont, via the LVRR owned National Docks railroad. This was double tracked, signaled 136 pound mainline, up until the early 60's. The Apollo and other pigs ran from the east side of the bay, over the bridge, as well. Remember the Valley had a pax operation out of the area of the LV carfloat operations, before trains were diverted to the Pennsy, via the Hunter connection. PA's started in freight service, and ended in freight/work train service. Using extra locos to run STA's, Locos laying over at 91 Bay street could be used anywhere, if they could be brought back in time to protect schedules. I will search my collection for anything interesting. Perhaps the one to ask for pics of PA's at National Docks locations would be LV-2? His collection, and those from his father, might contain the pic you seek......
