So far we can drive a train (video 1) and we can switch turnouts (video 2), all manually. To enable automatic train control we’ll need to create blocks. Similar to a real railway trains drive from block to block and they’ll be halted by a red signal if the next block is occupied.

At the entry of a block a track sensor detects a passing train (reed switch) or the presence of a train (current detection). Each sensor has an address. Traincontroller continuously monitors the sensors, at all times it knows which train is in which block on the layout.
