A grade crossing control system includes a controller that receives start and end inputs corresponding to a train traversing an outer approach, determines the difference in time between the start and end inputs, and uses the difference in time to determine a delay period by which activation of a grade crossing warning system will be delayed following detection of the train by a track occupancy circuit in an inner approach in order to compensate for slow moving trains. The start and end inputs for the outer approach may be supplied in different ways including a separate track occupancy circuit for the outer approach, by train detection devices unconnected to the track at the start and end of the outer approach, or by overlapping track occupancy circuits positioned at the start of the outer and inner approaches.
