Abstract [en]

Efficient and safe operation of freight trains require assessment of its running behaviour. As the freight trains get longer the Longitudinal Train Dynamics (LTD) part becomes more pronounced on its running behaviour in particular when traditional pneumatic (P) braking is used. In this context, tight S-curves in switches form a critical infrastructure bottleneck in terms of running safety. Moreover, the train composition influences the longitudinal dynamics. This paper looks at the LTD involving an open wagon-train with multiple wagon types passing through an S-curve. For this purpose, 3D-simulations of push tests with some input from the UIC 530-2 norms are carried out in the Multi-Body Simulation (MBS) software GENSYS. Parameters such as the buffer-type, wagon positions and loading are also varied. Static Longitudinal Compressive Force (LCF) limits for different cases are presented and discussed.
