So the 0-4-2 that I made this afternoon didn't quite go to plan:
There's a lot wrong with it. The tanks aren't tall enough, the lip on the bunker is too big, the list goes on. I can't get the tank taller while keeping the lip and top details at the right height, if anyone knows how to do this in Fusion360 please do let me know!
As it and the 14xx chassis that it fits are far too big to be the intended prototype I think it'll become a fictional class of locomotives for operating my fictional Newtownards to Portaferry branch.
When this line was built around 1898-1904 the CME realised that a class of modern tank locomotives needed to be built to operate passenger and goods trains along the line under the strict regulations of the Light Railways Act of 1896, and so a larger sister loco to the older 0-4-2Ts from Sharp, Stewart and Co found its way to the BCDR. Making the branch operate as a light railway was economical for the BCDR and apart from the construction of the locomotives there was no huge cost to opening the line. The locomotives had a light axle load, and the trains were usually relatively short.
Something like that, anyway...
