1895 this shortcut was supplemented by an even shorter shotcut from Graben-Neudorf via Blankenloch. This part still exists and today is part of the most used north-south line in the upper Rhine valley.
The line via Eggenstein became a less important branch line. Eventually passenger operation ceased 1967 and the northern part was dismantled. Only infrequent freight trains to a research center saved the southern part, as seen in this photo from the late 1970s.
