Interesting sub-topic Dave
I'm sure that you are aware of these options, but I'll throw them out for general consumption.
Depending on the amount of crew members I get, I can either do a dispatcher (the bare minimum, who writes their own orders), or I can incorporate the dispatcher with a "super operator", that handles all stations.
For OS, I once again took the cheap and reliable way out, and I use cheap, purchased from Target, FRS radios. The crews OS from all "open" stations (as listed in my timetable) to the dispatcher, with the crews taking on the role of "station operator". If they are close to the dispatcher, they don't need to use radios, they just talk to the dispatcher using the same verbiage they use over the radio.
For dictating and read back of orders, I have two FRS radios set to a different frequency that the operator and dispatcher use to talk to each other (keeps everybody else from having to listen to the chatter). These individuals sit in different parts of the basement, separated by about 20 feet, but two cement walls and about eight feet of dirt as the crow flies. (well, clay around here).
I have about 10 handsets, and two "foot pedals" for push to talk between the operator and dispatcher that I have not installed. I'm not sure that I want to go there. I need a power supply to make the system work, but more importantly, I need some sort of headset and/or scissor-stand for the dispatcher and operator. This old stuff is getting very expensive. Also, I'd have to string wire for the handsets, and unless I want a "party line", I'd have to rework the phone handsets with a push-to-talk feature.
Maybe, some day I will go down this path, but like the discussion with fast clocks, right now, cheap and dirty gets the job done. It has worked for 50 sessions.
I don't have either semaphore style or indicator light train order signals. If I do eventually decide to do actual train order boards / signals, I would go with the the NCE light driver and train order signals. That significantly cuts down on the wiring. The other thing I would want to incorporate if I do that is to have a panel for the operator to set the train order signals. I would incorporate this into a input board into the command station also.
I don't at this time do Form 31 train orders, only Form 19. I also use strictly "display" train order semaphores to "make the scene", and utilize colored cards on my fascia (red or green, red indicating a 19 order) to indicate that an order is waiting, which the operator will hang once completed for the crew on the bill box, or if it isn't written yet, the train stops until the operator walks the order over to the town.
The train order board westward now indicates that the crew must pick up an order. The eastward board is green, indicating no order. I went with a really dark green (I had a rattle can on the shelf) that unfortunately blends in with my black fascia, but there is no problem. It makes it REALLY easy for novice or boomer crews, if they simply remember the phrase "If it's not red, it's not red at all. If it can't be seen, it must be green".
So, simple solutions to required Train order challenges. KISS in practice.
