This simple circuit drives 6 LEDs in 'Knight Rider scanner mode'. Power consumption depends mainly on the type of LEDs used if you use a 7555 (555 CMOS version).

The first reed switch changes the signal to red as the train passes, then further along the track a second reed switch changes the signal back to green ready for the next train. The isolated section of track just in front of the signal is switched off by the relay when the signal is red so a train will stop automatically at the red signal. This project uses a 555 bistable circuit.
