The construction contracts for West Metro’s stations and rail line have been completed

The remaining work has been scheduled so that Länsimetro Oy can hand over the Matinkylä–Kivenlahti section to Metropolitan Area Transport Ltd in the autumn of 2022. At the same time, Finland’s largest infrastructure, HVAC and electricity and automation project will end. HSL will decide on the start of passenger traffic.

Construction and testing of the West Metro’s Matinkylä–Kivenlahti section has progressed to the stage where the five metro stations (Finnoo, Kaitaa, Soukka, Kivenlahti and Espoonlahti) and the rail line construction contracts ended on Friday, 13 May 2022. The Sammalvuori metro depot construction contract ended already in 2020. In April, the final testing of the systems ensuring passenger safety was carried out, and in May, the final approvals were obtained from authorities.

During the entire project, around 30,000 people were inducted in the various contracts, a total of around 2,100 person-years. The number of people working at the worksites was at its largest in November 2019, at 1,174 people. There were 905 companies involved in the various contracts.

The construction contract for the Finnoo metro station was carried out by a consortium formed by GRK Infra Oy and Aki Hyrkkönen Oy, while YIT Suomi Oy and Are Oy were responsible for the Kaitaa metro station, a consortium formed by YIT Suomi Oy and Are Oy for the Soukka metro station, and SRV Rakennus Oy and Kivenlahden Skanska Infra Oy for the Espoonlahti metro station. The rail line contract was implemented by GRK Infra Oy. The depot’s excavation and construction contract was implemented by the Sammalvuori consortium (Kalliorakennus-Yhtiöt Oy, EM Pekkinen Oy, Terrawise Oy and Aro-Systems Oy).

Alteration work on the overhaul track and night-time train depot underway to the west of Matinkylä station

“We are building one of the world’s safest metro systems. The remaining work will be scheduled so that we can hand over the section to the traffic operator Metropolitan Area Transport Ltd in the early autumn of 2022. At the same time, Finland’s largest infrastructure, HVAC and electricity and automation project will end,” says Ville Saksi, CEO of Länsimetro Oy.

On 9 May 2022, the restoration of the overhaul track and night-time train depot to the west of the current western terminal station Matinkylä began. When metro traffic continues from Matinkylä to Kivenlahti, the space in question will no longer be used as a service and storage area for metro trains, and the area will be available to metro traffic. The work will continue until 20 July 2022. Following the restoration work, Länsimetro Oy will hand over the final management of the Matinkylä–Kivenlahti section’s metro stations, rail line and depot to the traffic operator Metropolitan Area Transport Ltd in the autumn.

In addition, Länsimetro Oy is commissioning a park and ride facility at Kivenlahti, which will be completed in early 2023. Construction of the park and ride facility began in November 2021.

For commuters, the new rail section will provide a direct metro line to Kivenlahti. The new metro stations are Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. The length of the rail section available to passengers is seven kilometres. In addition, Sammalvuori has an underground metro depot. HSL will decide on the start of passenger traffic on the Matinkylä–Kivenlahti section.

The Project Manager presented a status report for the Matinkylä–Kivenlahti section of the construction project. Construction is progressing in line with the planned schedule and budget.

Alteration work on the overhaul track and night-time train depot will start up in week 19 to the west of Matinkylä station

The construction and testing of the West Metro’s Matinkylä–Kivenlahti section has proceeded to the stage where the alteration work on the overhaul track and night-time train depot to the west of the current western terminal station Matinkylä will begin on Monday 9 May 2022. When metro traffic continues from Matinkylä to Kivenlahti, the space in question will no longer be used as a service and storage area for metro trains, and the area will be available to metro traffic. The work will continue until 20 July 2022. The contractor for the alteration work is GRK Infra Oy.

The work will not cause disturbances in metro traffic. The loading of crushed rock and ballast may cause some noise nuisance in the vicinity of Hyljetie and Kaitaantie, and the smoke extraction fan may cause a whirring sound at the Tiistilä shaft.

The overhaul track to the west of the Matinkylä metro station has been used for servicing and storing metro trains at the western end of the operating metro line. When metro traffic continues from Matinkylä to Kivenlahti, the space will no longer be used for this purpose and the area will be available to metro traffic. The alteration work will take place between 9 May and 20 July 2022.

Loading of crushed stone and ballast at Hyljetie and transports to Kaitaantie service tunnel May–July 2022

Loading of crushed stone at the worksite base of the West Metro rail line at Hyljetie in Espoo will take place 26 May–1 June 2022, Mon–Sun from 7 am to 10 pm and loading of ballast will take place 13–17 June and 28 June–8 July 2022, Mon–Sun from 7 am to 10 pm. The loading operations may cause some noise nuisance in the vicinity. The aggregates will be transported from the Hyljetie loading area through the Kaitaantie service tunnel into the metro tunnel. Transports will be carried out at the mentioned times and they will increase traffic between the loading area and the service tunnel.

The loading area, service tunnel and transport route are marked in blue on the map below.

The crushed stone and ballast loading and transport work is related to the restoration of the overhaul track and night-time train depot to the west of the current western terminal station Matinkylä. The current use of the space as a service and storage area will end, and when metro traffic starts up, the area will be available to metro traffic. During the restoration work between 8 May and 15 July 2022, the smoke extraction fan of the Tiistilä shaft (Suomenlahdentie 15) will be used intermittently at low power between 7 am and 10 pm. While the fan is in use a whirring sound may be heard and dust may occur in the vicinity of the Tiistilä shaft.

We apologise for any inconvenience the work may cause.

Smoke-extraction tests to be carried out overnight at Finnoo and Matinkylä from 12.-13 April

The automation systems of the Matinkylä station, which is already open to traffic, the Finnoo station, which is under completion, and the rail section between the stations will be integrated during the overnight hours (11 pm–4 am) of 12.-13 April. The integration requires systems testing. The work may cause noise in the surrounding environment when the metro tunnel’s smoke extraction fans are tested. The area affected by the testing is limited to the Matinkylä and Finnoo stations and the rail section that runs between them.

The tests will be carried out at night when the metro is not running.
