The common use of UIC Pneumatic braking plant in long freight trains may involve time delays in the application of the braking forces along the convoy. This variable braking action along the train may cause heavy longitudinal efforts that could lead to wagons damaging and even cause train derailment. Simulations of these phenomena are very important both for safety and economic reasons since longer freight trains imply higher transport costs reductions. In this paper authors present simplified models used to evaluate, in a convenient time-saving way how train composition, buffers mechanical features, braking plant design and other key parameters may influence the longitudinal behaviour of the convoy.
