Smoke extraction fans will be test run on Wednesday 10 May 2017, starting at 6pm in the east shaft of the Lauttasaari station. The test runs will continue until later in the evening, and an occasional buzzing noise may be heard from the West Metro shafts during testing. We apologise for any noise disturbance.
The smoke extraction fans will be used in emergencies or during maintenance to blow smoke from underground areas through the shafts to open air.
A total of 32 smoke extraction fans have been installed in the Ruoholahti–Matinkylä section.
