Random generation of trains is an important topic for risk assessment of new train composition, which is of particular interest in this period in Europe.


This paper illustrates a new method to generate random trainsets, compliant with UIC CODE 421, which is the common standard followed by Railway Undertakings in Europe for international freight traffic.


In fact, there are several studies on new types of trains with distributed traction/braking that requires a statistical assessment of Longitudinal Train Dynamics (LTD).


Results reported in this paper show that the new method represents more accurately the target payload distribution of real wagons, with respect to the standard method currently proposed by the UIC CODE 421.


The new algorithm is suitable for the revision of UIC 421, as a novel way to generate random trains.

Keywords: Freight trains, UIC CODE 421, Random trains generation, Longitudinal train dynamics (LTD), Statistic analysis, TrainDy.
