The region’s suburban railway association (Zweckverband Stadt-Umland-Bahn Nürnberg–Erlangen–Herzogenaurach) is planning a line extension from Nuremberg via Erlangen to Herzogenaurach. As a so-called “L-network”, the urban and suburban transport system will have a route length of approx. 26 km and will be a technically compatible extension of the existing Nuremberg streetcar network.

With an estimated investment cost of around 372 million euros (price level 2019), road adaptation measures will be implemented and civil engineering structures along the line, as well as tracks and technical infrastructure will be realized.

The BERNARD Gruppe was commissioned with the design services for approx. 60 traffic lights, approx. ten level crossings and one driving signal installation, as well as for traction current, including general electrical engineering and telecommunication systems. The coordination of the interfaces with other experts, especially those in charge of transport infrastructure, represent a major challenge in the design phase.

The design services include all service phases according to the German fee structure for architects and engineers (HOAI), from permit application design to execution design, tendering and construction supervision. The project also comprises the conversion or upgrade of existing traffic lights systems. The new transport infrastructure will be designed in a way that minimizes its impact on traffic flow. This is essential in order to be able to guarantee the transport capacity forecast for the year 2035, which is particularly important for Nuremberg as a trade fair city.
