Quoting Alex Fojtik
... a 3 wide...is that a common train format?...
I made a fast research on 3wide trains and engines before building. And it is quite rare. Nevertheless I am still limited by the amount and type of my own bricks. That's why I chose this scale. Btw the first idea about the train was to build a minifig mini train like in Swiss Mini Steam Engine park which I've visited not a long time ago. I hope, I'll find some more time to build some other types of engines in this scale.
That's such a great MOC! I assume this is for the Creator train competition, right? Well, this sure is a great entry! I really like small trains and you have certainly done an outstanding job on this train! Excellent building! 5/5! :-)
