produced two options: both would leave the existing line just before the Hochstetten Altenheim stop and run straight ahead for about five hundred metres. The existing station would be relocated as a result. While one version would run through the middle of the towns of Hochstetten and Liedolsheim, the other would only pass through the outskirts of these towns. Under both options Hochstetten would receive another stop and Liedolsheim would receive a total of two stops. In both options the line would run through Rußheim to end at Philippsburg station on the Bruhrain Railway. Operations Timetable The "New Hardt Railway" is now integrated into the Karlsruhe Stadtbahn network as lines S 1 and S 11. Both lines run from Hochstetten through the centre of Karlsruhe and over the Alb Valley Railway towards Ettlingen. Between Karlsruhe and Neureut services operate at ten-minute intervals to about 9 PM. Services operate to Hochstetten during the same period at least every 20 minutes and there are a few services that terminate at Leopoldshafen. The DC-powered Stadtbahn vehicles operated by AVG on the line are similar in construction to Stadtbahnwagen B vehicles. Dual-system (AC/DC) vehicles were in use on the Hardt Railway only in 1991 and 1992. All stations have platforms with a height of 34 centimetres. Eggenstein Süd, Leopoldshafen Viermorgen, and Hochstetten Altenheim are request stops. Operations to KIT Campus Nord In the morning a total of two trains run to KIT Campus Nord (the north campus of the Karlsruhe Institute of Technology). The trains are decoupled at the Leopoldshafen Frankfurter Strasse stop with the front carriages continuing to Hochstetten and the rear carriages running to Campus Nord. The trip to Campus Nord can only be used by local staff, so a security check is performed shortly before the train reaches the site of the Campus Nord. Campus Nord station consists of two terminating tracks. Since there is no turning loop, the incoming set must be equipped for two-way operations or the departing trains must be operated in reverse (most Karlsruhe Stadtbahn vehicles are designed to only run in one direction normally). Two trains depart from Campus Nord in the afternoon peak hour. They wait at the Leopoldshafen Frankfurter Strasse stop for the train from Hochstetten, which is then coupled to the rear.
