The power supply unit ensures that the level crossing system remains in operation both under normal conditions, and also in case of power failure by using battery standby for a certain period of time.

The induction loop FSP (vehicle sensor type PINTSCH) is used for train detection. Strike-in (activation) and strike-out (deactivation) of the level crossing are controlled automatically via the induction loop whenever a rail-bound vehicle approaches or leaves a level crossing. Each loop is connected to an electrical unit (single loop detector module ESD) which processes if the loop is occupied or clear.

When a train stops on a level crossing the switching off of the level crossing protection system has to be suppressed until the train has cleared the level crossing. Especially in older level crossing protection systems this safety-increasing feature is not yet realised.

Supplementary to roadside signals and barriers, the audible alarm is an optional component for level crossings and bridge closure systems in order to warn pedestrians and cyclists. Moreover, it has been developed to replace electromechanical bells.

Manual switching equipment can control the equipment protecting a level crossing during shunting operations or during normal passage if necessary.

Barriers type SPK 6-6 and SPK 10-10 are designed for physically and visually closing off of a level crossing. The hydraulic free system is based on a mechanism with a circulating ball screw.

The purpose of road signals is to safeguard the danger zone represented by a level crossing. The St. Andrew’s cross gives rail-bound vehicles the absolute right of way. Signalling is preformed by means of light signals with the signal lamps SP200 and SP300.

In case of locally monitored level crossings trackside signals are located on the line ahead of the level crossing. They inform the train engine driver whether the level crossing has been closed and may be entered.
