In 1977, Deutsche Bundesbahn electrified the Gäu Railway, reducing the travelling time from Stuttgart and Zurich.
The Danube Valley Railway is still diesel-operated.

Since the 1960s, there have been numerous restoration projects at Tuttlingen station, which had been designed for a possible extension during its construction at the beginning of the 1930s.
Of the original eight tracks, five are currently still in operation.
With the closure of freight operations the freight tracks and many sets of points have been dismantled.
In 1992, Deutsche Bundesbahn sold the freight yard site to the city of Tuttlingen and the roundhouse site to a railway enthusiast.
Also in 1992, DB sold the west wing of the station building to an insurance broker, who then renovated it and rented part of it.
The east wing, which was retained by DB was fundamentally renewed in 1994.
A renovation of the facade, as has been done on the west wing, was not carried out, however.
DB closed the luggage counter in 1995, but in the same year established a travel centre.
