During braking, due to the interaction between the vehicles, longitudinal dynamic forces, characterized by different values and an irregular distribution along the train, develop in the train body, affecting the passengers` comfort or even the traffic safety. The paper is a parametric study having as objective to determine the influence of the number of coaches, vehicle weight and delay time of the development of braking forces on the size and distribution of the longitudinal dynamic forces developed in passenger trains during braking. The first analysis is based on the change in the number of vehicles which are part of the train. The second case analyzed refers to the total mass of the vehicles, which increases by 50% compared to standard train mass. In the third situation, there are taken into account variations of ± 20% of the length of the train overall pipe that are able to generate delays related to the occurrence and development of the braking forces at each vehicle of the train body.
