Semaphores or digital?

This depends entirely on the era of your layout and as with most signalling is down to modellers choice. Modern digital signals come in various sizes (2,3 and 4 light), so pick the sort that’s right for your layout.

Where to position

A good tip is to work backwards from a point of interest. A point or a platform is a good starting place. Always place signals on the left of the line and fix to the baseboard accordingly with any necessary wiring.

Manual or automatic?

This is down to the modellers choice. There is now automatic signalling on the market but for the modeller who wants to be more hands-on, run cabling from a control point to each signal so that they can be changed as necessary.

Automatic warning system

AWS is important with any signalling. Since the 1950’s driving over an AWS triggers an audible alarm and an indicator in the cab, these can be seen on the line as small squares in between the rails.
