WebJun 15, 2014 · Prior models have emphasized the impacts of reduced curving resistance, predicting relatively low absolute energy savings in low curvature track, i.e. that the absolute energy savings with TOR-FM is an exponential function of track curvature [3]. WebJun 15, 2014 · 1. Introduction1.1. Wheel/rail friction. Friction at the wheel/rail interface is understood to have significant impacts on wheel and rail wear, lateral (curving) forces, curve noise, and train energy (fuel usage) , , .In recent years industry focus has been on the separate control of friction at (a) the gauge face/flange interface (traditional lubrication) …
