The budget for Roslagsbanan's new trains is increased by billions

The 65 kilometer long Roslagsbanan passes through six different municipalities and is the backbone of public transport in the north-eastern part of Stockholm County. But the X10p type trains that operate the line are technically archaic and need to be replaced. They also have problems with cracking.

A few years ago, the regional council decided that all 31 vehicles of this type that run on the Roslag track must be replaced by 2032 at the latest. Place on stage for the new X15p model manufactured by Swiss Stadler. In autumn 2023, the first trains of this model were put into service.

But the money is not enough, according to a service statement. When it has now been decided to increase the purchase from 10 to a total of 15 vehicles, the budget must be increased, which the local newspaper Mitt i was the first to tell. The trains are expensive creations, so this is a substantial increase - from 1.387 billion to 2.287 billion kroner.

The service statement also shows that a new EU regulation, the Cyber ​​Resilience Act, has made the trains more expensive. The regulation came into effect in 2024 and dictates that trains must be cyber-secured. Stadler already pointed out in December 2025 that CRA-related measures could become significantly more extensive than previously thought.

- An investigation is still underway to clarify what technical measures are required and what financial consequences they have. Any additional costs resulting from the CRA are not covered by the current decision on the five additional vehicles, says Andreas Strömberg, press manager at the traffic administration.

Mitt i has previously reported that 21 X15p trains have been delivered, of which 14 are in service. However, the service statement advises against buying enough trains to cover the entire need. Instead, they are currently content with expanding the order by five vehicles.

- The vehicle acquisition is carried out in stages as a strategic choice of route. The order is now being expanded by 5 vehicles to a total of 15. The expansion is an important part of ensuring reliable traffic during the expansion of the Roslagsbanan to the city, says Andreas Strömberg and points out that there is still a need for 19 vehicles.

The reason for not making a major purchase is tactical.

- The traffic administration's assessment is that it is a sufficiently large volume to generate interest from several suppliers in a new procurement. A new procurement also provides the opportunity to set requirements based on the technology and regulations that apply at the time and reduces the risk of locking too large a part of the future vehicle fleet to today's vehicle generation.

Could this lead to vehicle shortages and passengers suffering?

- The planning is done so that the need for vehicles can be met when it arises. The continued procurement therefore needs to be carried out in such a time that the traffic is not affected by a lack of vehicles, says Andreas Strömberg.

When the Roslag line is extended from Universitetet station, via Odenplan to T-Centralen, the number of passengers is expected to increase significantly. In connection with the inauguration of the new route in 2038, a total of 60 trains are needed to meet the needs.
