Abstract:
1. A train control system for optimizing the control of a plurality of locomotives in a train consist including a Lead Locomotive and a plurality of Remote Locomotives, the system comprising: an operator interface located on the Lead Locomotive that receives input braking and throttle commands from a train operator; a control network connecting at least all locomotives and enabling transmission of throttle and brake commands to each locomotive, the control network being coupled to the operator interface; and a computer located onboard the Lead Locomotive that determines translated braking commands and throttle commands for each locomotive within the consist based on the operator input braking and throttle commands, the determination of the translated braking commands and throttle commands being made based on at least two of the track profile information, train consist information and temporary speed restriction information, wherein the translated braking and throttle values determined for each of the plurality of locomotives independently by the onboard computer are optimized in view of the train's fuel conservation, the reduction of in-train forces and maintaining the average train velocity and are output to each of the plurality of Remote Locomotives distributed in the consist to automatically control each of the plurality of Remote Locomotives in the train, wherein the train control system is capable of operating in a plurality of operation modes including a driver-assist DP mode, wherein receipt of an operator's input of a single set of braking and throttle commands pertaining to operation of the Lead Locomotive, and input via the operator interface, is automatically translated into corresponding braking and throttle commands for each of the Remote Locomotives, wherein the translated braking and throttle commands are calculated to minimize in-train forces and/or maximize fuel economy within selected parameters, wherein such translated braking and throttle commands are automatically implemented by each of the Remote Locomotives.
