Grounding Contacts

Grounding contacts are used to transfer current from stationary parts to rotating parts. In railroad applications, they are used to transfer the current from the bogie to the wheels. They thus ensure that there is a closed circuit. This runs from the overhead line via the wheels to the rail.

Grounding contacts are usually made of electrographite, i.e. carbon, with the advantage of minimizing wear and thus maximizing service life. In addition to the property that they make the train run, grounding contacts also have advantages in terms of safety: they protect passengers from electric shocks and are responsible for the illumination of track signals.
