The HKL Class M100 is the first and oldest class of metro trains in use on the Helsinki Metro. One train consists of two individually numbered cars. A total of 42 units (84 cars in total) were manufactured between 1977 and 1984.[1]

Up to six pairs can be combined into a 12-car train formation, however due to the relatively short length of the platforms (especially on the new Länsimetro extension), at most only two pairs (giving a 4-car formation per train; and prior to the Länsimetro opening in 2017 three pairs resulting in 6-car formations could also be seen during rush hour) can be combined for passenger service. Longer combinations are used in maintenance operations. Any Helsinki metro train types can be combined mechanically, such as for towing. The M100 series is the first train in the world to use VVVF propulsion inverters, developed and manufactured by Strömberg.[2]

The first three units (cars 101–106; nicknamed "nokkajuna", "beak trains") were constructed as prototypes in 1977 and had some minor technical differences compared to the later units. The prototype units were retired from service in 2021 and five of them were subsequently scrapped in Vantaa, with one unit preserved at the Helsinki City Museum.[3]

The M100s were refurbished twice: first in 2004–2009, at the Talgo Oy (now Škoda Transtech) rolling stock works at Otanmäki and secondly in 2019-2022 by VR FleetCare at its Ilmala depot,[4][5] to extend their lifetime until their planned retirement in 2030, by which time the class will be almost 50 years old.


Accidents and incidents

  • On 27 July 2016, M100 carriage no. 157 was involved in an accident with M300 unit no. 302 when the latter derailed near Itäkeskus metro station during testing.[6]
