A railway level crossing system, comprising two gates, each having a sensor 2.19 at the end, allowing the distance and angle between the gates to be monitored, and a sensor 2.11, to monitor the inclination of the gates lower members 2.10. If at least one sensors indicates that at least one gate is not closed i.e. within pre-set parameters, a signal is sent from the gate controller 2.15 to a traffic light controller 2.12 that turns red 2.4, and an automatic braking system that is activated. The traffic light remains red until all the sensors indicate that the gates are closed, and braking system actuator 2.8 is position a safe braking distance from the crossing. The sensors may be infrared or microwave actuated. Preferably the driver has to acknowledge the safe automatic braking of the train by pressing a button before moving the train again. Preferably an additional traffic light is positioned to prior to the light warning the gate is not in position. Alternatively if only one gate is used, the sensor from the second gate is positioned on a rigid vertical mast beside the gate, to allow the lateral position of the individual gate to be monitored.
