DB InfraGO and Siemens Mobility have developed and authorised an ETCS-based software solution that enables an increase in rail freight traffic on the new line between Bamberg and Erfurt, part of the ‘German Unity 8.1’ infrastructure project.
The new technology enables the operation of additional freight trains, particularly during the early morning and late evening hours, as well as at night. Railway companies can now apply for the relevant routes.
“With this new ETCS-based software solution, we are demonstrating how digitalisation can directly deliver additional benefits for our customers. Together with Siemens, we have developed an innovative solution that allows us to utilise the existing infrastructure more efficiently. In this way, we are creating greater flexibility for rail freight transport,” said Philipp Nagl, CEO of DB InfraGO.
The new technology enables more efficient use of the infrastructure
On high-speed lines featuring single-tube tunnels, a so-called ‘tunnel passing ban’ applies between freight trains – which travel at lower speeds – and high-speed passenger trains. This rule is necessary, amongst other reasons, due to the aerodynamic effects caused by the significant differences in speed between the trains.
The new software application links information from train scheduling, traffic control and railway safety systems and automatically identifies the type of train travelling on the route.
In this way, unauthorised encounters between passenger and freight trains in tunnel sections are technically prevented. The operational restrictions that were previously necessary can thus be maintained and further developed using a digital solution.
The new line between Bamberg and Erfurt is fully equipped with the European Train Control System (ETCS), thereby featuring one of the most modern rail control and safety technologies.
The route forms part of the ‘German Unit 8’ project and represents an important north-south connection within the German rail network. The line was designed as a high-speed axis. During the day, priority is given to high-speed passenger services, whilst freight trains mainly operate at night.
Rail freight transport on this route was gradually introduced in early 2025, and the line is increasingly in demand for freight train operations.
In order to operate on the VDE 8 infrastructure, locomotives used for freight transport must be equipped with the European Train Control System ETCS.
The new software solution developed by DB InfraGO and Siemens allows for more flexible use of the existing infrastructure and paves the way for the introduction of additional freight train services, particularly during periods of lower passenger traffic.
