Night-time testing of the West Metro’s safety systems in Matinkylä and Niittykumpu Mon–Tue and Tue–Wed, 4–6 November

An emergency shelter is currently being built in the Matinkylä metro station’s service tunnel. The construction of the emergency shelter also involves commissioning testing, during which the West Metro’s safety system will be tested during a fire alarm. The fire alarm will set off smoke extraction fans, for example. Testing cannot be carried out while the trains are running, it has to be carried out at night when traffic has ceased, between midnight and 4 a.m. The night-time tests will be carried out between Monday and Tuesday and Tuesday and Wednesday, 4–6 November. The tests will not affect metro traffic.

The West Metro has 52 technical systems of which the majority have to do with managing emergency situations. In connection with the construction of the emergency shelter, tests will be carried out to ensure that the systems will function also in adjacent facilities, i.e. the Matinkylä and Niittykumpu stations and the Tiistilä shaft.
