The wire (Ø 0,3 mm) that leads through this tube right underneath the baseboard, carries the waving arm on its upper end. Under the baseboard a crank is fixed to it, which is actuated by a connecting rod from the motor (just like a windscreen wiper).

The track on the viaduct is equipped with a train detection circuit (Uhlenbrock), which switches the waving drive once a train enters the viaduct.
A capacitor holds up switching off for a few seconds after the engine left the controlled section. So the man waves until the last carriage has left the viaduct.
