Abstract
A magnetic track braking device for a rail vehicle includes at least one pressure-medium-actuated actuation cylinder, which has a cylinder housing and an actuation piston movable relative to the cylinder housing, at least one magnet apparatus, which can be lowered into a low position onto a rail by the at least one actuation cylinder to generate, by a magnetic short circuit with the rail, a magnetic attractive force between the rail and the at least one magnet apparatus, and which can be placed, by the actuation cylinder, into a high position raised from the rail and into any intermediate positions between the low position and the high position; at least one high-position detecting apparatus, which generates a high-position signal when the high position is assumed by the at least one magnet apparatus.
