Hello, on my layout I have all MTH Pennsy Steam Engines and I am modeling the period of the mid 1940's.
I am running the MTH DCS control system.
I use Gargraves Track with Ross Turnouts.
I am working on my signal system and with some very helpful suggestions from a forum member named Stan, I am going to use a AIU to operate a few signals on my layout so I can change them from Stop to Proceed or visa versa when I wish and not have to rely on trackside sensors or isolated rails.
I have two fairly long passing sidings (32 O Gauge Cars) on my layout and I am trying to figure out what type of signal did the Pennsy use to show the train crew to take the siding ahead.
I looked up some information on this subject on the internet but they really don't go into much detail. Maybe I looked in the wrong place.
I am not sure if the Pennsy used a low 4 light dwarf signal or a 7 light position signal with a double head to indicate to take the next siding.
I realize possibly in this time period the train orders were handed up to the engine crew as they passed by an interlocking tower operator but this would be a bit hard to model.
I am going to York next week on a mission to look for some Pennsy signals.
Any information would be greatly appreciated !!!
