In 2017, the City Council of Helsinki decided to refurbish the M100 and M200 fleets in order to extend their lifetime for another 10 years. The renovation of the M200s started in early 2023, following the refurbishment of the M100s. They are being refurbished by government-owned VR FleetCare.^[8][9]

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.
