The present disclosure relates to a spring system comprising a strut for arrangement between a dolly and a body of a rail vehicle with a cylinder and a piston displaceably received in the cylinder which bound a piston chamber, with the piston or the cylinder being connectable to the dolly and the other of the components being connectable to the body and with one or more spring which cushion the body with respect to the dolly, with a non-resilient hydraulic system which is in communication with the piston chamber and by means of which the amount of the hydraulic medium in the piston chamber can be varied for the purpose of adjusting the strut length, with an abutment member being provided by means of which the end position of the piston can be changed in the cylinder and with means being provided which are made such that the means actuates the abutment member when the piston chamber of the hydraulic system is pressure-less or the pressure in the piston chamber or in the hydraulic system falls below a value.
