The hunting movement of the railway vehicles is essential for the safety, the comfort of the passengers and the integrity of the transported goods. The dynamic performance of a railway vehicle can be seriously damaged, due to the phenomenon of instability of the hunting motion that occurs when a certain speed is exceeded – the critical one. An important role is played by the suspension parameters in the extension of the stability interval during hunting motion at high velocities. And this is what the paper draws attention to, based on the analysis of how the elasticity and damping suspension characteristics influence the critical speed.
