The metro depot is an essential part of the metro infrastructure and a prerequisite for reliable metro operations. The depot is used for the storage, maintenance and servicing of metro trains.
The West Metro section includes one underground metro depot located in Sammalvuori, Espoo. The depot supports metro services on the West Metro section and is an integral part of the metro system as a whole. In addition to facilities for train storage and maintenance, the depot also includes staff facilities.
Länsimetro Oy owns the depot as part of its metro infrastructure. The depot facilities are leased to Metropolitan Area Transport Ltd, which owns the metro trains and is responsible for their maintenance and operation.
The metro depot is a large underground facility with a floor area of approximately 32,500 square metres.
The depot consists of separate areas for train storage and maintenance. It provides overnight storage for up to 20 metro train units and includes facilities for servicing and maintaining the train fleet.
The depot has been designed with energy efficiency in mind. Heating is provided by a ground-source heat pump system, while cooling utilises naturally cool groundwater.
