## Abstract

This chapter presents a mathematical model of coupler dynamics of Gatimaan Express. It has one locomotive class WAP5, one generator van, one second-class chair car, and one executive chair car, respectively. Overall, 180 (4 × 45) Degree of Freedom model is developed in Matlab/Simulink®. Lateral and longitudinal suspension forces of front bogie, rear bogie, and car body are considered in the model. The study is done with three different train’s velocities such as 40, 60, and 160 kmph, respectively. The actual track geometry provided by Research Designs Standards Organization (RDSO), Lucknow, is simulated for this study. The result of coupler forces and its rotations on these velocities are discussed.
