It's actually Gauge 1! I found some production references of the breakdown train and the coach on the Thomas Wiki, and so I decided to try building the coach. I hope to do the rest of the train as well as Thomas (and maybe Stepney) at some point, although it'll probably take a few years to do. It'll be in the green livery, and those two big windows will be covered as well, I just haven't done it yet. Thanks for the kind comments.
