This tweet shows the image below and says:

Soyuz rocket on its way to the launch pad (on a train of course).

Question: Does this Soyuz vehicle (a train engine) burn coal or oil? Does it have an official name?

    $\begingroup$ There is no white steam visible, so it could not be a coal fired steam engine. $\endgroup$ – Uwe Aug 7 at 6:53

    $\begingroup$ Google translates "мотовоз" as 'motor vehicle'. I think uhoh is looking for the type designation, which is TEM-2. $\endgroup$ – Hobbes Aug 13 at 15:07
  • $\begingroup$ @Hobbes. I think that "an official name" not equivalent to "vehicle model". If we talk about the Russian dictionary, then this word does not really mean what is shown in this photo. But if you use Google to search for words in this context - "мотовоз"+"Байконур", you will find the local meaning of the word at the cosmodrome. For example youtube.com/watch?v=U-qHJzbn7Ag youtube.com/watch?v=AsBIm55cjqc Word "мотовоз" at Baikonur means a locomotive with one or more cars. youtube.com/watch?v=22P9x0qBByc Details of the Baikonur railway are described in this video. $\endgroup$ – A.
