Koskela depot project

Upon completion, the Koskela depot will serve as a main depot for tram traffic in Helsinki alongside the Ruskeasuo depot.

A sizeable new construction project will begin at the Koskela depot in 2024 once the Ruskeasuo depot has been completed and has enough depot capacity for the duration of the construction in Koskela. In the Koskela depot project, the current depot facilities, some of which are up to 80 years old and no longer fit for purpose, are being replaced with a new depot. The project also involves overhauling the track maintenance facilities connected to the depot.

Upon completion, the Koskela depot will serve as another main depot for tram traffic in Helsinki alongside the Ruskeasuo depot currently being built.

The key objectives of the project are as follows:

  • The quality level of the depot project will support cost-effective operations during the lifecycle of the depot.
  • We will serve as pioneers in promoting environmentally responsible construction projects.
  • We will stay on schedule and within the allocated budget.
  • We will find the best solutions for promoting the project together with different operators
