Hey, I would be interested in 1 or 2 complete sets if these become available.

Dear Jukki,
Thank you! I will post here all the process, but I can't promise, that the process will be fast.
With best regards,
Alexey

Re: Sm2-sähkömoottorijuna
Dear railway enthusiasts,
I’m trying to figure out the train numbering system and can’t understand it. That is, the first digit is always 6, the second digit is 0 for a motor car, and 2 for a trailed car, and then the serial number of the train? If a motor car has a number, for example, 6092, then the trailer car will be 6292, or do motor and trailer cars not necessarily work as part of the same electric train and can be intercoupled?
With best regards,
Alexey

Hi Aleksei!
You have understood the numbering of Sm2-Eioc pairs pretty much correctly: The Sm2 motor units are numbered from 6051 to 6100. The corresponding Eioc trailer car number is gained by adding value 200 to the motor car number. For example, Sm2 6051 and Eioc 6251 are a pair, and Sm2 6100 and Eioc 6300 are another pair.
Sm2 and its Eioc wagon cannot be decoupled during normal operation. I'm not sure if these original Sm2-Eioc pairs have ever been mixed.
Cheers,
LOK

Re: Sm2-sähkömoottorijuna
I read from Valtionrautatiet 1962-1987 book (pages 406-408) that VR bought Sm2 trains in 4 batches: The first 20 Sm2 trains were ordered in 1972 and these Sm2 units were numbered from 6051 to 6070. Corresponding Eioc trailer cars were numbered between 6251 and 6270. VR ordered more Sm2 trains in 1975, 1977 and 1978. Each of these later batches contained 10 Sm2 trains so the total amount of Sm2 trains was 50 units. The completed trains were handled to VR between June 1975 and December 1981.
This batch production of Sm2 trains might explain why some units seem to have different chassis structures. Perhaps Sm2 blueprints were updated as VR and the manufacturer gained experience from the first Sm2 trains. The book also has a picture of Eioc 6281 in yellow-brown livery without any markings of the cabin door in the front. Perhaps the later Sm2 batches were built without the front doors thou there is no clear mention about it in the book.
