Indian Freight system is facing huge competition. The average speed of wagons at 40-50 kmph for empty wagons faces huge hunting problem. In these paper Indian parameters are studied using a numerical model The numerical model is consist of a whole wagon with two conventional three-piece bogie running on wheelsets. The wheel-rail contact is considered with heuristic nonlinear creep model for both single point and two point contact. Coulomb friction model is considered for contact between the truck and bolster. The present study concentrates on the critical hunting which is mainly depending on primary and secondary suspension parameters. A numerical study is run in Matlab to obtain the optimum parameters for increasing critical speed to stabilize wagon for both increased speed and at loaded vehicle.
