A COMPUTER SYSTEM FOR TRAIN PERFORMANCE CALCULATIONS

This paper is concerned with the application of digital computers to train performance calculations. It describes how, starting with the calculation of minimium running times and associated performance variables, BR have extended their computer methods to the construction of data information systems for running times and for route geography, design evaluations, freight train maximum load calculations and energy minimization studies. Significant developments in train performance since 1960 are outlined, and the present system is fully explained. The use of the system by various departments--engineering, planning and research--is described, and emphasis is placed on the satisfactory relationship between programmers and engineers which has been established, and its consequential benefits. Illustrative examples of typical applications are given.
