Following on from the planned connection of the new line from Wendlingen – Ulm to Ulm main station using relay signal box technology, further construction stages will be required to implement the final permanent construction stage. To achieve this, the existing relay signal box is to be replaced by an electronic signal box.
The ESB-A at Ulm main station is due to be integrated into a regional operating centre in order to also take into account additional ESB-A at the planning stage (Günzburg and Neuoffingen) along with the existing ESB-A at Neu-Ulm.
