soviet AA20 4-14-4 (gulag express)

65.9k winterro  2.0 years ago

the AA20 is the largest steamer that ever drove the rails in europe, it had a 4-14-4 wheelbase and could pull 3000 tonnes of freight (or the gulag express). it was very slow at 42 mph and destroyed the rails it drove on in a curve. after that accident it was sent to scrap (R.I.P gulag express). CONTROLS: throttle to drive, roll to steer. (can somebody make this work on railway mod?)

    Steam engine with working pistons gets my support all day long! The scale of ambition to get a 4-14-4 to work with functioning pistons is impressive! I just hope this gets the votes it deserves.

    after all the hours I've been on this site, I've never seen a soviet train before, even if I search it up, still, no crap pops up and slaps me in the face, I think I've found the one that actually did slap...
