The joint test run testing of the Aalto University station has ended. The fire tests were run again to ensure the systems function together. It will be possible to estimate when metro traffic will start after joint test runs of three stations have been conducted.
The purpose of the joint test runs is to test the different systems, such as building technology, safety automation, power supply monitoring, physical access control, fire-extinguishing systems, reserve power and smoke ventilation, in various emergencies and their restoration to normal after an emergency. The joint test runs will be conducted at every eighth station and on the rail line.
The final joint test runs at the Aalto University station were acceptably completed last week. A short and long power cut, fire on the platform and on the line, and preparedness for flooding were tested at the Aalto University station.
“The first joint test run has now been successfully completed. The experiences at the Aalto University station will be utilised at the other stations. This week, the operation of individual systems will be ensured before the joint test run at the Tapiola and Keilaniemi stations,” says Matti Kokkinen, CEO of Länsimetro Oy.
The joint test run will include the suppliers of various systems, contractors, Helsinki City Transport (HKL) and the emergency services, if necessary. The situation will be monitored on site and from Helsinki City Transport’s metro control room in Herttoniemi, where the metro’s operations and traffic are overseen. At the same time, it will be possible to conduct joint test runs at two stations.
“The testing phase will take longer than expected, but it is necessary for starting traffic. The date of starting traffic will become clearer after joint test runs of three stations,” says Olli Isotalo, Chairman of the Board of Länsimetro Oy.
The Rescue Departments of Espoo and Helsinki will approve the security systems on the basis of the test results. After this, the building authorities of Helsinki and Espoo will be free to approve the use of the stations and rail tunnels. Helsinki City Transport (HKL) will ensure that the track engineering security systems are working properly. Helsinki Region Transport (HSL) will decide when passenger traffic begins and when feeder bus lines start operating.
