An electrical machine has a braking element and a release device. A rotor of the electrical machine includes the braking element and release device. The electrical machine is located, for example, in a rail vehicle. In order to brake the rotor of the electrical machine in the event of an error in the drive train, an overload torque is generated by the electrical machine. An overload clutch is triggered by the overload torque.

A locomotive is disclosed. The locomotive includes a car body, including an operator cabin, a power source, and an operator health monitor within the operator cabin, the operator health monitor configured to monitor at least one health condition associated with the operator and configured to generate an operator health signal associated with the at least one condition. The locomotive includes an operator warning system within the operator cabin, configured to present the operator with an operator warning in response to an operator warning signal, and an electronic controller. The electronic controller may be configured to determine an operator fatigue score based on, at least, the operator health signal, determine if the operator fatigue score exceeds a warning threshold, and transmit the operator warning signal to the operator warning system if the operator fatigue score exceeds the warning threshold.

A monorail vehicle includes two bogie assemblies supporting different ends of a chassis. Each bogie assembly includes guide wheels rotatably connected to a bogie frame, a wheel assembly for rolling along a top of a guide beam, and a drive unit. The drive unit includes an electric motor attached to the bogie frame via a mounting flange that is located within a first lateral half of the body, a brake unit, and a planetary gear assembly coupled to a rotor of the electric motor. The planetary gear assembly is located on a first side of the electric motor and the wheel assembly is mounted to an output of the planetary gear assembly. The drive unit is attached whereupon the wheel assembly may be dismounted from the drive unit in a direction of a second lateral half of the body without dismounting the drive unit from the bogie frame.
