Level crossing with barrier

I0.0 Train is in the crossing from right
I0.1 Train is in the crossing from left
I0.2 Train coming from right
I0.3 Train coming from left
I0.4 Barrier is up (right side)
I0.5 Barrier is down (right side)
I0.6 Barrier is up (left side)
I0.7 Barrier is down (left side)
O0.0 Let barriers down
O0.1 Switch the white signal (clear)
O0.2 Switch the red signal

Trains may approach a level crossing with a barrier from both directions. When a train is approaching, the barrier must be closed in good time and the traffic signal must be switched to red with the track-signalling unit. When the train has left the crossing and no further train is approaching, the barrier can be reopened and the traffic light can be switched over.

  • 2 sensors for detecting whether a train from the right or left is on the level crossing.
  • 2 sensors for detecting whether a train is coming from the right or left.
  • 2 sensors for detecting whether the barrier is open (left or right).
  • 2 sensors for detecting whether the barrier is closed (left or right).
  • 1 actuator for closing the barrier.
  • 1 actuator for switching on the red signal and 1 actuator for switching on the white signal.
