PRR had a Rusty Rail procedure, It was a lever blocking device and a sign to place on the interlocker handles for switches. They reminded the operator to double check against his own knowledge of area traffic before he lined a move that depended on the track circuit of a little used route. PRR/PATH had a fatal side swipe with a switcher at Hudson tower in ’63 in which failure to do this was the key factor. See the ICC historical accident investigations, picts too.Bill |
