I had a reprint of the original version of The Little Engine That Could when I was probably 3 years old, but I completely forgot about it as an adult!  I've been on the lookout for a good opportunity to make a tank engine style steam loco, and somehow this thing happened out of the (medium) blue.  It runs very well, but my depletion of parts for the Blauhaus Building forced a bunch of aesthetic compromises.  Most importantly, the boiler should be a bit taller and it should have a more consistent cross-section.  Perhaps eventually, once I have more parts, I'll revisit this, but for now, I must consider it a very successful and happy little project!
