ERTMS, which stands for European Rail Traffic Management System, will eventually replace all national signaling systems in Europe. This will not only improve punctuality but also make cross-border travel easier.

Mantenas competence

The expertise and holistic approach was crucial when Mantena won the contract to install ERTMS equipment on board the trains, as a subcontractor to Alstom.

First, the LTR-17 work machines were equipped. Then, all 11 trains on the Gjøvik Line were fitted with ERTMS and delivered back to the train owner by the end of 2023.

"Mantena's skilled professionals have made a significant effort in bringing Norwegian trains into the digital future," says Tore Løveid, Division Director for Products and Projects at Mantena.

Delivered on Schedule Despite Challenges

Unfortunately, in May 2024, Mantena had to take the unfortunate step of terminating the agreement with Alstom due to prolonged non-payment for work performed. Mantena tried to find solutions with Alstom, but the payments from Alstom did not materialize.

"The installation of ERTMS involves a lot of manual labor and customized installation procedures for each train type. We have invested significant time and resources in building competent and efficient installation teams, a unique expertise that we will carry forward into future assignments," says Løveid.

Despite several factors beyond Mantena's control that have created challenges in the project, Mantena has consistently delivered according to the schedule communicated to Alstom.

Reduces Risk of Error

Today's railway signaling systems are based on old technology and are highly prone to errors. ERTMS transitions the signaling system to a data and communications-based system, which essentially means that today's light signals are moved from the tracks into the trains. Less equipment in and along the tracks reduces the risk of errors.

The new signaling system is scheduled to be gradually implemented across the entire railway network by 2034.
