During the commie era they hyped such train stories here. I kinda remember one about an attack toward north against the Czechs in 1920 by the Hungarian Soviet. They might used those trains but I've no idea how much of the story was real or made up. I suspect it was a copypasta of the stories of the war you mentioned as the leadership from the Muscovite School built the system with ready made propaganda packages they received from their masters.
