If one day I come to Russia, I'll try to go on this line
Are the RA1 in operation on other lines? I suppose they do, but I hope you won't think that my question is stupid.

Of course they are. Most of RA1 operate in Western part of Russia. Some RA1 can be found even in Moscow region on unelectrified lines.
You're always welcome to Russia

Thanks for your answer!
I hope I'll be able to go to Russia one day.
