摘要： A train control system and method uses signal information from a next block to change a restrictive signal in a block currently occupied by the train to a less restrictive signal if it can be ascertained that the condition causing the more estrictive signal has changed. This may be accomplished by receiving signal information from the next block while still in the current block and, if the signal information from the next block is no more restrictive than the signal information in the current block, and the signal in the current block is of a type that can safely be modified, allowing the train to operate as if the signal information for the current block were less restrictive than the actual, previously received signal information for the current block.
摘要翻译：列车控制系统和方法使用来自下一个块的信号信息，如果可以确定导致更严格信号的条件已经改变，则将当前由列车当前占用的块中的限制信号改变为较少限制性的信号。这可以通过在仍然在当前块中从下一个块接收信号信息来实现，并且如果来自下一个块的信号信息不比当前块中的信号信息更多的限制，并且当前块中的信号是可以安全地修改的类型，允许列车操作，就好像当前块的信号信息比当前块的实际先前接收到的信号信息的限制性更小。

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 and/or distance and speed from a wheel sensor over the distance is also collected. The wheel rotation information and distance and/or speed information are then used to determine the size of the train wheels and/or a correction factor that can be used to correct the information from the wheel sensor for wheel wear. 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.

摘要： A method and apparatus for actuating a train horn use the speed of the train to determine when to start a horn sequence such that the horn sequence complies with all applicable regulations. In one embodiment, an engineer enters a command, such as by pushing a button, when a predetermined distance from a grade crossing is reached. A processor then determines the speed of the train from a tachometer. The speed is used to determine how long it will take to reach the grade crossing. Preferably, this calculation is repeated until the time to reach the grade crossing is within a window during which the horn sequence must be started. The processor or other device then causes the horn to sound in the required pattern.

摘要： A method and system in which a vehicle carries an on-board positioning system and has access to a database of information pertaining to a plurality of fixed paths. A vector between the position of the fixed path and a position of the vehicle as reported by the positioning system is calculated prior to arriving at a point of divergence (i.e., a point at which a path branches, such as a switch on a railroad track). After passing the path divergence, a second vector is calculated between the position of the vehicle as reported by the positioning system and at least one of the alternate paths, preferably the correct alternate path. The first vector is compared to the second vector, and a determination as to which path the vehicle is on is made based on the comparison.

摘要： A method and system for providing true failsafe control of an electronic braking system by a train control system which controls a switch that supplies power to the electronic braking system. When the train control system determines that it is necessary to activate the train's brakes, it controls the switch so as to remove power to the electronic braking system, which results in activation of the train's brakes. In highly preferred embodiments, the switch is of a type that is normally open and that requires the presence of an electrical signal to close the switch to supply power to the electronic braking system. In such embodiments, any loss in power to the train control system will result in a loss of signal to the switch, thereby causing activation of the train's brakes.

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 controller determines that an end of train (EOT) has passed a point through the use of positioning systems at the head of the train (HOT) and the EOT. In a first method, the controller obtains the HOT position at a point of interest from the HOT positioning system. The controller then determines when the train has traveled a distance equal to the length of the train and then interrogates the EOT positioning system. If the difference between this position and the position reported by the HOT positioning system at the point of interest exceeds a threshold, then the EOT has passed the point. In a second method, when the HOT positioning system reaches a point of interest, the position reported by the EOT positioning system is integrated until the total distance traveled by the EOT equals the length of the train.
