Block signals and semaphores?

how did a road crew with a

in pre-radio days. The operator would indeed be involved but at least on the
Q at places like Eola,and W Eola, there was a specific methodology used. It
did not involve the operator going outside to hoop up a note,nor the crew
stopping to talk to someone or a note with orders when starting out as that
would
have been too many hours in advance and things changed. What did these places
and more physically have in common ?
I suspect this method of communicating was in widespread use across the Q and
other RR's. Probably was used at Cicero to advise inbound road crews what
trk. to pull into in 'D' yard.
Again here's two clues: you could model this on your layout and be able to
see it. At least at one location in Chicago on the Q/BN it was used well into
the 70's to communicate track(unloading side) information to passenger trains.
Remember as in many things on the RR is was suprizingly simple and immediately
understood.
