A fun little deviation from my usual steam locomotive MOCs. Thomas was my gateway drug into the world of steam railways. The design was actually a lot trickier to figure out than I anticipated, and I'm not 100% happy with how it turned out - but it'll do.
I plan on incorporating this engine into my planned Lego railway layout too. Steam railways here in the UK often have "Thomas days" where one of their usual locos gets painted blue and fitted with a face, as an attraction for children. So this engine will represent that.
