signal use

[NW Mailing List]

Well now we’re in to what was my N&W territory (Asst. Trainmaster in Sandusky). I didn’t pay too much attention to down there.

Thoughts: while N&W did route signalling, PRR/PC/CR did speed signaling. And that signal is governing a train coming off PRR/PC/CR (after PRR sold the Sandusky line to N&W, they retained trackage rights between Colsan (Bucyrus) and Carrothers for trains to/from Toledo) so would it be displaying an N&W Diverging Clear/Approach or a PRR/PC/CR Medium Clear/Approach?. If the latter, it’s correct.  

As for the dwarf, the Toledo line west of Carrothers was double-track ABS (current of traffic signaled only for that direction). Every track needs a signal at an interlocking but why spend the money on a high signal for a move that should normally never happen (southward (the Carrothers Branch as it was officially called was north/south) train on the northward track). But looking at the N&W westbound signals from behind, it looks like Diverging Approach was the best you could get from the N&W “westbound” (it was TC (CTC) territory) track to the Carrothers branch northward track (there’s no vertical possible on the lower head). From a 1980 CR ETT I have, the Toledo line went to single track (Rule 261 TCS (CTC)) six miles north of Carrothers. It’s possible there were no intermediate signals in between so that might be a Diverging Approach with a Medium Clear/Approach at the next signal six miles ahead.
