Lumikko’s sister company, Lumikko Huoltopalvelut Oy, won the public tender organized by Pääkaupunkiseudun Junakalusto Oy for the overhaul of SM5 train HVAC* systems.

Quality and schedule in focus
Jani Luoma, Fleet Director at Pääkaupunkiseudun Junakalusto Oy, shares his goals and expectations for the upcoming collaboration.
“The essential thing is to keep the trains running at all times. For us as the customer, schedule and quality are the most important factors, with the goal of minimizing warranty work. We have strong confidence that Lumikko Huoltopalvelut is the right partner.”
The overhaul work will begin in 2025, and the contract will be in effect until 2030.
A significant contract for Lumikko Huoltopalvelut

“We look forward to collaborating with Pääkaupunkiseudun Junakalusto Oy. Our goal is to ensure a pleasant passenger experience and maintain the reliable operation of the train fleet’s HVAC systems well into the future.”
“This is a historically significant contract for us, and we are extremely proud to have been chosen as the partner. The project supports our strategy and will provide employment for our skilled personnel in the coming years.”
The contract covers the refurbishment of HVAC systems in 41 train cars. The refurbishments will be carried out at Lumikko Huoltopalvelut’s facilities.
56.1 million journeys per year
SM5 trains are modern urban trains supplied by the Swiss company Stadler Bussnang AG. They operate in the Helsinki region on routes such as Helsinki-Kerava, Helsinki-Kirkkonummi, and Helsinki-Helsinki-Vantaa Airport. In 2023, SM5 trains carried out 56.1 million journeys per year.
The first pre-series SM5 trains entered service in 2009, while the latest ones were introduced in 2017.
The overhaul work is scheduled in a way that ensures it does not impact train operations or the service for passengers.
