Track circuit semaphore signal demo

A demonstration showing how a block detector can be connected directly to a Servo Controller setting up a track circuit for a semaphore signal.

Every time a locomotive enters the block the semaphore signal automatically drops to danger until it is clear. This sets up fully automatic signals on your layout.
