    • 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.
    • 列车控制系统包括控制模块,该控制模块使用定位系统确定列车的位置,并且咨询数据库以确定列车何时接近由轨道电路监视的轨道的一部分。 当火车靠近轨道电路时,但是当列车仍然远离轨道电路足够远时,使得列车可以在到达由轨道电路监视的轨道部分之前停止,列车向收发机发送询问消息 与轨道电路相关联。 当轨道电路接收到询问消息时,开始测试。 测试结果被传回火车。 如果轨道电路没有响应或指示问题,火车将采取纠正措施。
