Abstract: A device configured to operate an electromagnetic rail brake, comprising: a tank configured to store a hydraulic fluid, a pressure accumulator, a pump device configured to the feed the hydraulic fluid from the tank to the pressure accumulator in order to load the pressure accumulator with a pressure, a brake connection that is coupled or couplable with the pressure accumulator in order to provide a brake pressure to the additional brake device of the rail vehicle; and a suspension connection to a hydraulic device of a two stage suspension, wherein the suspension connection is coupled or couplable with the pressure accumulator in order to provide the actuation pressure to the hydraulic device.

Abstract: A holding device for an electromagnetic rail brake of a rail vehicle, the holding device comprising: a holding element including a spring configured to support the holding device at a chassis of the rail vehicle; a movable actuation bolt connected with the holding element and couplable with the electromagnetic rail brake; and a hydraulic unit connected with the holding element and the actuation bolt, wherein the hydraulic unit is configured to move the actuation bolt between an idle position in which the electromagnetic rail brake is inactive during operations of the rail vehicle and an active position in which the electromagnetic rail brake is active during operation of the rail vehicle in response to hydraulic fluid flowing into the hydraulic unit or hydraulic fluid flowing out of the hydraulic unit.
