The Trossingen Railway (Trossinger Eisenbahn, TE) is a DC-electrified branch line in the German state of Baden-Württemberg.

The railway is not part of the Deutsche Bahn network; instead it is owned by Stadtwerke Trossingen GmbH.

Therefore, committed citizens of the town tried in subsequent years to improve the transport situation and when the state railway had shown no interest they ended up agreeing to establish a private company.

Because a power station was built nearby in Trossingen at the same time, the projected line was to be electrified.

Since the 1990s, the line has been considered in danger of being closed, but instead it was saved by being integrating into the Ringzug concept of the Schwarzwald-Baar-Heuberg planning region.

However, two vintage railcars were temporarily restored to scheduled operations from December 2004 because the Ringzug was short of rolling stock.
