The Kraich Valley Railway (German: Kraichtalbahn) is a branch line in southwestern Germany running from Bruchsal to Menzingen.

Therefore, Bruchsal sought a railway in the Kraichbach valley through the towns of Ubstadt, Unteröwisheim, Oberöwisheim, Münzesheim and Gochsheim to Eppingen.

The northern line would run through Odenheim to Elsenz and the southern branch up the Kraichbach valley to Gochsheim.

Originally planned to run only as far as Gochsheim, it was finally decided to extend the line out of the Kraichbach valley to Menzingen.

The line was initially operated by the Westdeutsche Eisenbahn-Gesellschaft (West German Railway Company, WeEG).

The Kraich Valley and the Katzbach Railways were the two most profitable lines operated by BLEAG in the early years of the twentieth century.

After the district of Karlsruhe agreed to contribute to the funding of various BLEAG routes, the lines were temporarily saved.

In the wake of the bankruptcy, both of the BLEAG lines in the Kraich Valley and the Katzbach were taken over by the German Railway Operating Company (Deutsche Eisenbahn-Betriebs-Gesellschaft, DEBG) on 1 January 1932.

The steam locomotives and passenger carriages on the line, which were up to fifty years old, were gradually replaced by diesel haulage from the mid-1950s.

In 1980, several new factories were established in Gochsheim, which led to a marked increase in freight traffic on the Kraich Valley Railway.

From October 1981, services were reinforced on the Kraich Valley Railway by class NE 81 diesel multiple units, which had been built by Waggon Union.

In the 1980s, the workshop facilities in Menzingen were expanded and modernised at a cost of millions of Deutsche Marks.

Originally it operated the line with class NE 81 diesel multiple units that it had taken over from the SWEG or acquired from Maschinenfabrik Esslingen.

At this time, the Bruchsal–Ubstadt Ort section was already electrified, so Stadtbahn sets were operated between Bruchsal and Ubstadt as part of the celebrations.

In September 1996, the Kraich Valley Railway was finally incorporated into the operations of the Karlsruhe Stadtbahn.

Services run through Karlsruhe Central Station (Hauptbahnhof) to Baden-Baden and Achern or to Freudenstadt over the Murg Valley Railway.
