Abstract
A rail vehicle equipped with a support actuator of variable vertical length mounted between a vehicle body and a running gear located underneath. In order to maintain an operational supporting device and adequate ride comfort after a failure or overload of the support actuator, an emergency spring coaxial with the support actuator is provided, which only becomes effective when the stroke of the support actuator falls short of a preset value.
