Hey joel_don, I've go to tell you how lucky you are! Getting to take apart an old rr station! Do you get to keep anything you want? Now about you're "orderboard". That's actually a "semaphore", a type of signal that depot agents, switchmen, and locomotive train crew, especially engineers and brakemen, would use. The semaphore would have a long arm that when activated, by hand and levers, would either drop or raise. At it would, a light inside the semaphore would be covered by either a red, yellow, or green lens. This would tell the engineer, when aproaching a station, whether to stop, slow down, or continue, if not on the schedule for that train. Not only did the lights tell the engineer whether he needed to stop, slow down, or go, but also the position of the signal arm. If the arm was pointing straight up, it meant "stop" or "danger". If the arm was at an angle, it meant "slow down" or "proceed with caution". And laying down (picture an L) it meant "all clear" or "proceed". We have one of these at the RR museum I volunteer at here in NC. If I were you, I would either keep it or sell it. (Or you can give it to me... I'm a HUGE trainnut and I've always wanted one of these. Plus, my birthday's next week
) Here is a chart of the arm meanings and a picture of the one at my RR museum. Let me know if you find anything else! (Or if you want to give it to me as a birthday gift!
) Good luck!
Blessings,

(Oh, if you ever want to sell ANYTHING rr related, well, you know who to call!
)
Really? MAN!!!!! 
I would give it a great home! My room is covered in rr memoribilia, lanterns, signs, lights, tools, china, etc. What if I posted a few pics of my collection? How much do you want? (I cannot afford $150 and up) I would really LOVE to put that in my collection... I have it on my list (with about a million other things)... bummer. Well, I hope you can complete the depot purchasing. Let me know if you find anything... The one thing I am looking for, except that signal 
, is the board that hung either inside or outside a station where station and platform agents wrote down the trains, what time they pulled in, what time they pulled out, and where there going. That would be amazing to hang on my wall! Something like the pic below... Hope you have a good b-day! Keep me in mind please, because next week, on my 18th b-day, I will be testing for my Drivers License! 
Good luck with everything and God Bless!
