    摘要: A train control system requires a train operator to enter signal aspect information at each wayside signal position on a railroad and stops the train if the operator fails to enter aspect information without communicating with the wayside signal device to verify that the information entered by the operator is correct. In some embodiments, the signal aspect information is entered by pressing a button corresponding to the signal aspect information, and the location and/or arrangement of the buttons changes. Alternatively, the operator must repeat a varying sequence (such as a series of button pushes) in conjunction with and/or in addition to entering signal aspect information.

    摘要: A train control system includes a control module that determines a position of a train using a positioning system and consults a database to determine when the train is approaching a portion of track monitored by a track circuit. When the train is near a track circuit, but while the train is still far enough away from the track circuit such that the train can be stopped before reaching the portion of track monitored by the track circuit, the train transmits an interrogation message to a transceiver associated with the track circuit. When the track circuit receives the interrogation message, a test is initiated. The test results are transmitted back to the train. The train takes corrective action if the track circuit fails to respond or indicates a problem.

    摘要: A method and system for compensating for wheel wear uses position and/or speed information from an independent positioning system to measure some distance over which the train has traveled. Wheel rotation information is also collected over the distance. The wheel rotation information and distance and/or speed information are then used to determine the size of the train wheels. The method is performed periodically to correct for changes in wheel size over time due to wear so that the wheel rotation information can be used to determine train position and speed in the event of a positioning system failure.
