Donald and Douglas (Thomas & Friends)

Donald and Douglas are supporting characters in Thomas & Friends. They are two black Scottish tender engines that live and work on the North Western railway.

Why They're Really Useful Engines

 * 1) They were the first twin engines to arrive on Sodor and are very enjoyable and entertaining to watch.
 * 2) Even though they bicker a lot, they refuse to be separated and always apologize to each other afterwards, unlike Bill and Ben.
 * 3) They also got to return to the show beginning in "Sodor’s Legend Of The Lost Treasure" with the help of Andrew Brenner.
 * 4) Their fond memories of the Scottish Highlands are always pleasent.

Bad Qualities

 * 1) Even though they did return in the Andrew Brenner era, and had a spotlight episode in Season 20, they don’t get that much screentime. Plus, their bickering in "Emily in the Middle" did get rather annoying.
 * 2) In the US dub of Season 6, they dropped their Scottish accents because of the toned-down narration from a depressed Alec Baldwin.
