ABSTRACT:
A train throttle and brake control apparatus is provided for use in a train having a master locomotive and one or more slave locomotives remotely located in the train. In a first embodiment, the apparatus includes a train force calculator which approximates train coupler forces based on computations as a function of the track topography. In a second embodiment, a coupler sensor is provided which senses the forces transmitted by the couplers on the slave locomotives. In either embodiment, a position determining device is included which provides a position signal based on the position of the train. A storage device stores a track database containing track topography information. A controller uses the coupler force computations or measurements, the position information, the track topography information, train consist information, and locomotive control settings to generate slave control signals which are provided to the slave locomotives through a communication device.
