order board at the Durham, NH train station
At one time all train stations had order boards on the roof -- a type of a semaphore signal to tell the train crew when to stop or when the line was clear. A few still have them just for display purposes, not (obviously) for signalling. Like the ones in Reading and Andover, the metal part of this order board is stamped "B&M Signal Department," and is probably original. The blades and lenses are almost certainly modern additions though, since they are in such perfect shape.
