Testing of West Metro commuter safety systems begins at Kaitaa

The testing of more than 50 different technical systems in case of emergencies, such as power outages and fires, has begun at the Kaitaa metro station. The metro service is expected to start up between Matinkylä and Kivenlahti during 2023. Approved station-specific simultaneous test runs and testing of all of the systems is necessary before passenger traffic can begin.

The various technical systems, many of which are located on several floors at the ends of the metro platform and in the metro tunnel’s facilities, are a part of modern metro infrastructure that is invisible to passengers. The systems are largely related to passenger safety in emergencies. While every single device and component has been subjected to point testing and the systems have undergone test runs, only the simultaneous operation of all of the systems in different emergencies is proof that the station is ready for the metro service to start up.

The first emergency test will be carried out at the Kaitaa metro station halfway through October. First up is the testing of the systems’ operation during a short and long loss of power supply. In connection with the power outage test, also the systems’ operation during flooding will be tested. Towards the end of October, fire testing will take place at different points in the metro tunnel and station. All-in-all, the station testing will take around 4–5 weeks.

Blackout tests ensure the operation of critical equipment

Power outage tests ensure that the station’s electrical systems operate in different types of power outages of varying lengths. The power supply to equipment that is critical for the operation of the station is ensured through automated feed exchanges and double feeds, a standby generator or UPS (Uninterruptible Power Supply) devices. If the power supply is lost, the functioning of these devices is tested using blackout tests, simulating faults in the transformers supplying the station and checking the feed exchanges’, standby generator’s and UPS devices’ correct operation, and testing the operation of related devices during a power outage.

Systems start up automatically in a fire test

In a metro tunnel fire testing situation, a fire alarm detects an increase in heat in the tunnel, after which the systems operate automatically. The station’s and connecting tunnels’ over-pressurising systems are activated, the evacuation announcements start and the lighting, locking, info screen, elevator and escalator controls operate automatically as required by the emergency.

The first step in the fire tests is to ensure that the station is in its normal operating mode, i.e. all of the devices have been set to their normal metro service mode. The fire alarm will be activated from a predetermined mode, using a fire alarm or call point. The fire alarm is relayed to the automated systems, the metro control room and, in an actual situation, to the emergency services. Based on the location of the fire, the automated systems turn on automatically-activating smoke compartments and escape route over-pressurisations, turn off the ventilation, control the station’s lighting, open the locking of escape routes, close fire doors in public spaces, turn on the correct evacuation announcements (depending on the fire’s location) with which metro passengers are directed out along a safe route, relay the evacuation messages to the passenger info screens, control the camera surveillance system, turn on the elevators’ evacuation drive mode and stop the downward escalators.

Testing proceeding station by station

The joint testing of the systems will take place one station at a time. The testing involves not only the metro station, but also the operation of the systems on the rail area adjacent to the station.

“The operation of the systems is monitored during testing both onsite and in HKL’s control room in Herttoniemi, Helsinki. Different scenarios focus on testing different systems. If a specific area is not functioning as planned, the test will be repeated until the systems operate exactly as they were designed to do,” explains Commissioning Engineer Janne Ilkanheimo from the West Metro project.

In addition to the five new metro stations (Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti), also the operation of the Sammalvuori depot will be tested. The interface between the Matinkylä metro station and the new section was successfully tested in August.

The testing phase will be followed by approvals from authorities, the preparations for starting up the service made by HKL (Helsinki City Transport), which operates the trains, and the preparatory measures by HSL (Helsinki Region Transport) on the part of feeder traffic, for example. The metro service is expected to start up between Matinkylä and Kivenlahti during 2023.

Pedestrian and bike path along Soukanväylä to open to traffic in October

The pedestrian and bike path built along Soukanväylä will open to traffic on 1 October 2021. The path is a combined bike path and footpath. The pedestrian and bike path was built as part of the landscaping for the Soukka metro worksite’s Soukanväylä worksite area, which took place in the spring and summer. During construction, the builders accessed the worksite through a service tunnel and exit shaft along Soukanväylä, which meant that it was not possible to open the pedestrian and bike path earlier due to safety reasons.

Along Soukanväylä are the metro’s service tunnel and exit shaft. Once the metro is completed, the Soukanväylä service tunnel will be used periodically for maintenance on the Soukka metro station. The exit shaft is related to the metro’s safety, serving as an emergency exit from the metro tunnel for commuters. There are nine exit shafts along the Matinkylä–Kivenlahti metro section.

Testing has now begun on the West Metro’s Matinkylä–Kivenlahti section, which is currently under construction. During the autumn and winter scenario testing will be carried out, testing the functioning of the metro station, adjacent stations and rail line systems in various exceptional situations, such as during power outages of different durations and in case of fire. This ensures that the modern metro infrastructure will operate safely also in emergencies.

Smoke extraction fan tests to take place at Matinkylä and Finnoo weeks 35–37

Smoke extraction fans will be tested at the Matinkylä and Finnoo metro stations and on the rail sections and the shafts (Tiistilä shaft at the address Suomenlahdentie 15 and the Suomenlahdentie shaft at the address Suomenlahdentie 22) between them at night between 30 August and 19 September (weeks 35–37). During the testing, a whirring sound may be heard in the vicinity from time to time. The smoke extraction fan tests will be carried out at night between 11:45 pm and 5 am when the metro is not running. The plan is to use the smoke extraction fans at the lowest power possible to avoid making noise. Between 13 and 19 September (week 37), there will also be noise resulting from fire testing at the Matinkylä metro station; the fire alarm will sound near the bicycle parking area at the eastern entrance, under the Suomenlahdentie bridge.  

Smoke extraction fans are used in case of fire to blow smoke away from the underground facilities along fire-compartmented routes into the outside air. There are smoke extraction fans in the metro line’s vertical shafts and at the metro stations’ eastern and western ends. The testing of smoke extraction fans is related to the testing of the West Metro’s Matinkylä–Kivenlahti section. The functionality of the systems is also always tested at the adjacent station, i.e. in Finnoo’s 
case, testing will also take place on the systems of the already operating metro station at Matinkylä. All in all, 15 smoke extraction fans have been installed on the Matinkylä–Kivenlahti section. There are 32 smoke extraction fans on the Ruoholahti–Matinkylä section.  

We apologise for any inconvenience caused by the testing.

The situation concerning updating the co-operation agreement between Länsimetro Oy and HKL was presented to the Board of Directors. HKL reports to Länsimetro Oy on the use of the Ruoholahti–Matinkylä section rail line and stations and related service and maintenance tasks as stated in the co-operation agreement. The co-operation agreement between Länsimetro and HKL that was updated on 27 November 2019 is valid until the Matinkylä–Kivenlahti section is open to the public. The new co-operation agreement was drawn up in the course of spring 2021 and is, for the most part, completed. The aim is to have the Board resolve on and sign the agreement by the end of 2021.

The Board authorised the CFO or a representative appointed by him to launch a tender process for and conclude an agreement on financing for the Matinkylä–Kivenlahti section project up to a maximum of EUR 60 million in one or more loans. The tender for financing will be carried out jointly with the City of Espoo’s finance department. Financing for the project is proceeding according to plan.

Länsimetro Oy’s CFO presented the cost monitoring and budget for procurement decisions for the Matinkylä-Kivenlahti section. Construction is progressing in line with the project plan’s budget.

Construction will continue near many of the new stations after metro service starts – focus on bicycle parking

The Espoo City Board decided, on 10 February 2020, that some of the West Metro’s park and ride spaces for cars will be replaced by high-quality bicycle parking in the vicinity of the metro stations. According to estimates, the number of bicycle commuters using the park and ride facilities at all of Espoo’s metro stations will total 3,100 in 2030 and some 3,900 in 2050, which is more than twice the number of passenger car commuters.

A review has been carried out of the possibility of adding park and ride spaces for bicycles along the West Metro, and design guidelines for the bicycle park and ride facilities have been drawn up by the City of Espoo. Länsimetro will build at least the bicycle and car park and ride spaces specified in the project plan and, where possible, carry out quantitative and qualitative improvements on bicycle parking also at the Espoo metro stations already in use.

The Finnoonsilta entrance will initially provide 72 covered park and ride spaces for bicycles and another 142 spaces will be located in connection with the Finnoonsillta underpass.

The popular city bike service will not be available in the vicinity of the new stations at the time when the metro service starts. It will be possible to expand the city bike service in 2026 when the next agreement period for the city bikes begins. City bikes | espoo.fi

Construction work near the stations will affect commuting

Some of the park and ride spaces for cars and bicycles cannot be implemented until the other construction work being carried out in the vicinity of the metro stations has been completed in the next few years. The construction and development of the stations’ surroundings also has an impact on when the various metro entrances can be opened for passengers. In Kivenlahti, for example, passengers will have access to only one of the station’s two entrances – the Kivenlahdentori entrance – when the metro service starts. At the Finnoo station, the incomplete construction work near the station will affect commuting for years to come.

Ilmakuva Kivenlahden metroaseman Kivenlahdentorin sisäänkäynnistä.
The Kivenlahdentori entrance will be available to passengers when the metro service starts. The Kivenlahdentie entrance will not be open to passengers when the metro service starts due to other construction ongoing in the area. This entrance will be opened once construction in the area around the entrance is completed.

An electronic signage system will guide commuters to the park and ride facility, indicating the number of free spaces. The signs will be installed on the main roads: Länsiväylä, Soukanväylä and Kauklahdenväylä.

Länsimetro Oy is, however, preparing for future urban development by building the entrances so that the metro will cater to the needs of its users also in the future. Passengers must be guaranteed safe and accessible movement at all stages regardless of the construction work being carried out in the vicinity of the metro stations.

On West Metro’s website you can see the location of the stations’ entrances and the arrangements for moving at the stations, and the progress and schedule of the construction work.  More detailed information on the arrangements for moving in the vicinity of the stations will be available as the start of the metro service approaches. According to estimates, the new section will be opened for traffic during 2023. The timetable will take shape as the testing phase advances.

Wanderers sculptures now completed at Kivenlahti station!

Art will be incorporated into the architecture of every metro station along the Matinkylä–Kivenlahti section. The aim is to make the stations more attractive, inviting and recognisable. The metro stations will feature art in various forms – light, sound, paintings and sculptures.

The pair of sculptures by Kalle Mustonen called “Wanderers” is the featured work of art at the Kivenlahti terminal station. The installation of the sculptures on the station platform began in March 2021 and was declared completed in the review carried out in late May. This was the culmination of a long process. Mustonen began to sketch the Wanderers in autumn 2018, after which he made a scale model of the sculptures and prepared working drawings. He began creating the full-sized pair of sculptures in October 2019, and the 17-month-long journey came to an end with the review in May. In the autumn, a competition will be held to name the work of art.

The terminal station’s landmark consists of two wooden figures that are approximately two and three metres high. The humorous figures, which appear to be running in the middle of the metro platform, are endearing and will stand the test of time. Created in warm wood, the sculptures contrast with the otherwise light tones of the metro station. ALA-Architects is responsible for the architectural design of the station.
