Trains entering the staging yard are automatically routed to the first free track. If a siding is free, HADES switches the associated turnout. Before the exit switch, a short section of the siding is de-energized. As soon as the integrated track occupancy detector detects a power consumer, the entry switch is set and the section after the entry switch is de-energized. The train stops, regardless of whether the locomotive is pulling or pushing.

The basic module monitors and controls the first two sidings. An additional track module monitors and controls 2 further sidings (max. 15 track modules can be connected).

In the event of a fault, the LEDs flash and the exit of further trains is blocked. If only the track voltage has failed, operation continues with the last settings after switching on again.
