The invention relates to a coil device for an electromagnetic track brake for a rail vehicle. The coil device has a winding wire, which has a first end and a second end. The coil device is the first end of the winding wire is formed as a first coil connection for establishing an electrically conductive joint connection to a first connection cable and/or the second end of the winding wire is formed as a second coil connection for establishing an electrically conductive joint connection to a second connection cable.

A frictionless electromagnetic braking system utilizes linear alternators which are controlled by a power electronics converter interface to capture the car's kinetic energy and generate braking force on the wheel. The alternators are engaged by means of driver or operator input.
