Sm1 "Sami" EMUs

The class Sm1 were the first Finnish EMUs on the newly built electric network around Helsinki area. Revolutionizing the railroading in 1970s today these units are worn out and slowly being withdrawn once they brake down, and finally all will give way to modern class Sm5 Flirt EMUs. The inside sources of VR-Yhtyma operating these are telling that they are in the "terminal care" meaning no more rebuilding going on and once they are tired the units will be put in front of the torch at the VR Hyvinkää rolling stock works. We will make effort to catch as many of the roster with a camera as long as it's possible.

Finnish railroad organizations and railroad operators have their own pages, as well as the largest operator VR-Yhtyma and a newcomer to the field Junakalusto.

The Sm1 local EMUs have been the backbone of Helsinki commuter traffic since the early 1970s when they replaced Dm7 diesel rail cars plus steam and diesel engine hauled local trains. At its heyday the 50 unit "Sami 1" fleet provided the commuters for the time great and reliable way to get to work and back home. Progress in EMU technology happened though and the trains have also aged severely. The handicaps in the early 2000s were already obvious: more failures on the way, high floor making it difficult of impossible to transport bikes, luggage, wheel chairs, baby carts, older passengers, etc. Year 2010 the unit 6008/6208 was the first to retire and more rusty, windows broken and fixed with stickers units are following it one by one, replaced by the air conditioned and modern fleet of the Sm5 Flirt trains.

The Sm1 will probably be the only part of the VR rolling stock not ultimately receiving any of the salad green livery.

VR-Yhtyma Sm1 unit 6001/6201 at Helsinki Main, Finland

The first number in series Sm1 EMU number 6001/6201 has brought its passengers to Helsinki Main track 4 in the morning rush hour traffic. After other Sm1 and compatible Sm2 units pile up behind the end couplers the train, the consist will be taken to the Ilmala depot for a few hours rest. During the afternoon and the evening rush hours, it will be in service again.

The 6201 is the half with the traction equipment, 6001 is just a driving trailer. The units are _always_, without any exception arranged so, that the coach is towards Helsinki.
