The FM - types are called in Russia TE10 ( M or U for example) the M62 has a 2 stroke V - engine that could be partially been copied from GM - types but had the much more better sound. Single M62´s had been used in former eastern Germany too and it had been reported that they were able to destroy window glasses based on the deep frequency engine noise when used without a muffler in the early years....
Some interesting downloads for the MS - trainsimulator are also available there so you could get the engineer´s feeling driving a TE10 or M62 too.
