New control and signalling technology: modernisation of the Ansbach-Triesdorf line

More reliability and flexibility thanks to modern control and signal technology • Preliminary work has begun • Construction starts 3 May


Deutsche Bahn (DB) is upgrading two ageing signal boxes in Ansbach and Triesdorf to electronic signal boxes (ESTW). The lines Ansbach-Triesdorf and Leutershausen-Wiedersbach-Ansbach-Wicklesgreuth will be equipped with modern control and signalling technology, while the level crossing in Kleinbreitenbronn (a district of the town of Merkendorf) will be renewed.


Construction began with excavation work at Ansbach station on 3 May. A new central signal box will be built, together with an operator workstation station from which train dispatchers can control the new signal box in Triesdorf. This will be followed by extensive cabling work along the line, where points and newly erected signals will be connected to the modern control and signalling technology. This will improve train dispatching through continuous operation from the electronic signal box in Ansbach and offer more travel options in stations during regular service and construction works. Overall, the network will be less susceptible to faults and the maintenance effort will be reduced.

These new systems are planned to go live in the second quarter of 2022. Detailed information on construction work and possible disruptions to rail travel is being compiled and will be published shortly. Unfortunately, even with the use of cutting-edge equipment, there will still be some construction noise. We apologise for any inconvenience and ask for your understanding.



The federal government has provided €500 million for modern signal box technology – from the economic stimulus package to combat the consequences of the coronavirus pandemic. Within a short time period, existing signal boxes and level-crossing safety technology in seven regions will be modernised with digital signal box technology. In close cooperation with industry, processes are currently being optimised and standards established to significantly accelerate project handling.


Thanks to this ambitious project, Digitale Schiene Deutschland (DSD) is creating industrial jobs and supporting medium-sized companies in Germany. Digitalisation also transforms public transport and helps protect the environment. Train passengers are already travelling largely CO2-free. But with smart, digital signal boxes and the European Train Control System (ETCS) offering Europe-wide standardisation, more trains can be used on the same routes. Digitalisation is revolutionising sustainable rail transport: with shorter travel and waiting times and more accurate customer information.
