The B&O W-1 was a proposed locomotive design that sadly never saw the light of day. Instead of having 2 big outside pistons like a conventional locomotive, this design had 32 smaller inside pistons, all in the name of having more slow-speed manoeuvrability.
Of course, none of this really matters. This is a locomotive design I find just so fascinating, and I've never seen anybody try and remake it in any videogame, let alone Minecraft. I thought it would be a fun challenge, and I think it turned out quite well.
