The points are set and the exit signal of the two-track station area switches to Green. The first loco passes the points and enters the one-track section through the level crossing. It stops at the end of the track and waits. After some seconds the loco returns to its place.
The points are set for the second train. The exit signal switches to Green again. The seconde train passes the points through the level crossing and waits at the end of the track. After a short period of time it returns to its place, too.
The exit signal clears the track, as soon as the points are set correctly. The warning lights at the level crossing keep blinking from departure of the train until it has passed the level crossing. The locos speed up and slow down slowly in both directions. Travel speed, acceleration and delay can be adjusted. At each stop there is a short break.
Once the sequence has started it runs through completely. It can only be re-started after it has finished.
Setup: DC track voltage, one points, one exit light signal, train detection through reed sensors or track occupancy indicator, flashing light for the level crossing. After activation two trains go back and forth a line one after another. The layout has one light block signal and a level crossing with two flashing warning lights.
A simple setup that can be operated with direct current only. Can alternatively be started with a DCC command. The sequence runs completely with DC. The varying voltages for the three track sections and changing polarity for returning are done by the U8.

- Reed contacts at the end of the three track sections avoid the train to run over the end of the track.
- Two reed contacts to both sides of the level crossing are used to stop the blinking of the warning lights after the train has passed.
- The reed contact behind the exit signal resets the signal to Red after the loco has passed. On its way back the train begins to slow down here.
- The reed contact near the end of the one-track section triggers the slow-down of the train as well.
- The Light 32 supplies the voltage for the track (both directions). Both locos go with direct current in a pure analogue set-up.
- If the layout is very short adjacent reed contacts can be put together. I.e. one reed contact can have more than one function within the sequence.
- You can adapt the position of the reed contacts according to the length of your commuter train layout.
