• During a visit with a customer a small watercolor caught my eye. The painting showed a shed-like building perched on top of a single pole by a railroad crossing that had been done in the 1920s. Apparently these buildings were railroad signal towers. Located at intersections that were heavily traveled, the signal operator would notify oncoming trains whether the rail was open along the line so that the train could approach without slowing down or stopping. I gathered some historic images of towers in Florida and have posted them below since they make great precedent for playhouse design. Does anyone know if some still exist around the state?
