The surviving section of the railway, which lies wholly within the borough of Bad Salzdetfurth, serves today mainly as a tourist and commuter line.

What little freight traffic had remained between Lamspringe and Bad Gandersheim (sugar beet, other agricultural goods, and wood) ceased 29 May 1994.

While the construction of Kassemühle bridge west of Sehlem took the existence of the Lamme valley line into account,[2] no overbridge was provided near Lamspringe.

[3] While the remaining section between Groß Düngen and Bodenburg was threatened with closure in the 1980s and 1990s, too, it was spared at the instigation of the federal country and of the town of Salzdetfurth.

In order to save expenses on a level crossing, the old Bodenburg station was vacated, and a new halt was opened some 400 m (1,300 ft) east as the new terminus of the line.

The Bad Gandersheim–Lamspringe section is nowadays an asphalted foot and cycle path, passing several sculptures and extensive natural hedges on its course through the Heberbörde, an open, hilly stretch of countryside.

The two large viaducts in the municipal area of Bad Gandersheim, built around 1900 from quarried stone, are listed as buildings of historical importance.
