Hello,

this is a Soviet broad gauge locomotive fabricated in Luhansk in Ukraine and mainly used in freight transport.
Each of the two sections houses a 10 cylinder two-stroke opposed piston diesel engine generating 3000 horsepower (2200 kW).
In 2005, some locomotives were fitted with 16 cylinder engines to prolong their service life.
Apparently, the TЭ10 locomotives also bear the epithet "earthquake" because they shake the ground when they start. The engines sound really cool, btw.

With photos provided by Roman_95 who works with these locomotives I could build the interior as well.

After pasting the schematic, you might have to use a debug stick to set both ends of the deepslate tile walls that form the exhausts to "low" and up to "false".

Enjoy!
