THE EFFECTIVE GRADIENT TECHNIQUE IN TRAIN PERFORMANCE CALCULATIONS

One of the critical features of a computer program to simulate train performance is its ability to manipulate efficiently the data describing the track geometry. The gradient and curvature data together determine the equivalent gradient resistance which, in turn, plays an important part in any simulation involving section times, maximum train loads and train speeds. In this paper the effective gradient technique is introduced. This technique reduces significantly the computation required to assess the effects of track geometry on the performance of a train.
