A rail vehicle suspension system (20) comprises a supporting structure (25), a suspended structure (48) and a primary spring (26) between the suspended structure and the supporting structure. An actuator (28) is connected to a first structure amongst the suspended structure and supporting structure, and has a free end portion (51) movable relative to the first structure between an extended position and a contracted position. The actuator is operative to catch a second structure amongst the suspended structure and supporting structure and bring the supporting structure into the close position when the free end portion moves to the contracted position. A secondary spring (44) is connected to the second structure amongst the suspended structure and supporting structure and positioned such that the secondary spring is unstressed by the actuator when the free end portion of the actuator is in the retracted position.
