Donald and Douglas

Donald and Douglas (originally known by their old numbers, 57646 and 57647, respectively) are twin Scottish mixed-traffic engines, specifically Caledonian Railway McIntosh 812 class engines. Douglas tagged along with Donald to Sodor in order to escape from scrap, despite Donald being the only engine expected. After proving themselves to be really useful, they were both allowed to stay. They now work as utility engines on the NWR; working wherever they are needed. They work primarily on The Little Western, but sometimes on Edward's Branch Line (Railway Series only) and the Main Line.
