Abstract: A control arrangement for a railroad level crossing is disclosed. The control arrangement comprises monitoring sensors for monitoring the level crossing, the monitoring sensors arranged to detect an obstruction within a restricted area at or near to the level crossing, and a processing unit associated with the monitoring sensors and arranged to generate an alarm warning when an obstruction is detected. The alarm warning is used to adjust a Movement Authority issued to a train approaching the level crossing.
