NETWORK APPROACH TO BRAKE PIPE LEAKAGE

Network models are presented to describe the effects of brake pipe leakage. The pressure distribution along the brake pipe of a multi-car train is treated through either of two ladder network models. Each network section represents a single car length of brake pipe and contains a series element and a shunt element. The two models differ only in the shunt element selected. This element may be either a flow sink or an orifice. In both models the overall effect of leakage depends on its location relative to the locomotive. When the leakage occurs further from the locomotive it exerts a larger influence on the pressure distribution. These leakage effects are formulated in quantitative terms from the models.
