Quite some time ago, we received photos from a (then) SEPTA employee, Bob Boguski, of the Philadelphia area. He wanted to share some views of one surviving Reading tower, at Wayne Junction.
Inside a tower, there is usually one or more model boards. The model boards show simplified diagrams of trackage being controlled somewhere in the outside world. The track being controlled is often an interlocking plant, a big collection of railroad switches allowing trains to be moved between tracks or onto sidings or branches.
Colored lights on the model board represent positions of railroad switches in the plant, as well as the indication of trackside signals. Small pushbuttons or toggles on the model board allow operators to remotely throw the railroad switches and change signal indications. A close up view is shown below.
The signals and switches are interlocked, or linked in a controlled manner to avoid dangerous situations. For example, two trains would (hopefully) be prevented from approaching each other on the same track.
If you know what you are doing, the lights and buttons shown below allow you to throw switches to move trains safely and efficiently between tracks.
