Paper shows the basic concepts for an automatic identification procedure of several parameters of a brake pipe pneumatic model. The procedure is on a hybrid metaheuristics scheme that involves the radial basis functions. Automatic procedure is applied to pneumatic module of TrainDy, UIC software for computation of Longitudinal Train Dynamics (LTD) of freight train. Such pneumatic module has been validated by a manual identification of parameters in order to create a device library of the most commonly used braking devices of European freight trains. Results show the reduction of the error by means of this procedure that could be further improved to consider also other aspects, such as the local curvature of time evolution of air pressure in brake pipe.

The procedure is on a hybrid metaheuristics scheme that involves the radial basis functions. Automatic procedure is applied to pneumatic module of TrainDy, UIC software for computation of Longitudinal Train Dynamics (LTD) of freight train. Such pneumatic module has been validated by a manual identification of parameters in order to create a device library of the most commonly used braking devices of European freight trains.
