A train equipped with an onboard system for determining its position and a track database for determining the positions of upcoming grade crossings sends activate after expiration messages to control wayside warning systems at the crossings to achieve a constant warning time while maintaining a safety margin that ensures the train can be stopped if the wayside systems do not respond correctly to the activate after expiration messages. The system may be used in place of existing track-based crossing warning system control circuits. Communications between the train may be radio-based, and may be direct between the train and wayside devices or may be routed through a central station, which may act as a relay or maintain a database. The train may control multiple crossings at onetime, thereby eliminating the need for downstream adjacent crossing control.
