Usual and conventional design that uses a sensor at each approach and a sensor at each end of the island
Good when train speed is constant and train obeys the speed for which the crossing was designed
For example, if a crossing is built based on a 30 km/h train, with a 25 second warning time, a train going 60 km/h will trigger a 12 second warning time, etc.
Because of the island circuit, the crossing is cleared as soon as the train clears the island
For crossings with higher speeds and more hazardous, at least two wheel sensor detectors are recommended as a redundant train detection mechanism
The Normal Crossing may include additional features, such as:
The Evaluator can be equipped with a connection to the Control Centre of the Operator and/or Maintenance Supplier
The Control Centre receives real-time data about the status of the Level Crossing
The Control Centre can activate the Level Crossing remotely
The Evaluator can be equipped with an Event Recorder to record all operation
All recorded data can be accessed remotely and wirelessly
Optionally a White Light may be installed for the Train Driver alongside the track, signalling the status of the crossing. If the white light is on, it's ok for the train to cross the road. If white light is off, then train must stop, blow the horn and advance when crossing is clear
The Crossing can be either powered by solar power, wind power or by the electrical grid
