An expert system for heavy haul train operation

In railroads, the learning of how to operate trains by an apprentice operator needs always to be reviewed by an experienced engineer. This project proposed the development of an Expert System to aid the operation of trains, seeking to obtain better operational procedures, establishing the safest and smoothest operation, optimising the fuel consumption and facilitating the training of new operators. The Expert System uses an on-board computer installed in the locomotives and obtains input data from information collected in sensors installed and controlled by the on-board computer. Checking the captured data, the Expert System consults a Repository of Knowledge, registered by Specialists of Train Operations, and sends advising messages to the train engineer, according to the most appropriate rule for the situation of the moment. By analysing all the trips made by the engineer, it is possible to find that trip that was the most economical, the safest and most efficient. The proposal of using on-board computers to recover that knowledge, applied in a trip, and to make available to him later through an interface man-machine, emitting advising messages, is shown to be quite efficient. Statistics obtained in CVRD (Companhia Vale do Rio Doce), where the project is being evaluated, demonstrate that just a reduction of fuel consumption in order of 1% would result in an economy of US$400,000 (four hundred thousand dollars) a year.
