Donald and Douglas (originally known by their old numbers, 57646 and 57647, respectively) are the Scottish twin engines on the North Western Railway. Donald is 9, and Douglas is 10.


57646 and 57647 were designed by John F. McIntosh, and built in 1899 for the Caledonian Railway in Scotland. They worked there until the rise of diesels in the late 1950s. They named themselves Donald and Douglas. Being almost 60 years old, and very obsolete, their class was ready for retirement and scrap. In 1959, the Fat Controller ordered Donald to come to Sodor to help with the goods work. Douglas was to be scrapped, and since the two couldn't bear being separated, they hatched a plan. Douglas snuck out with Donald, and both engines came to the Island of Sodor without their numbers (on purpose). The Fat Controller was very surprised and annoyed. Donald and Douglas claimed they had no way of telling each other apart, so the Fat Controller decided to keep both of them while he made a decision to decide which engine was to be sent away. Donald and Douglas tried their best to do well, but it was hampered by many things. The first was an incident where Douglas accidentally shunted Thomas's special coach into the express coach line, causing delays at the station. The second was when Donald accidentally crashed into a signal box, which upset the Fat Controllers arrangements to send Douglas away. The third was a brake van who was very horrid and spiteful. He caused lots of trouble for Donald, Douglas, and James. Eventually, while helping James up the hill, Douglas accidentally smashed the brake van into pieces. The Fat Controller was very stressed and waited until around December, when the snow was very heavy. Donald and Douglas were used to heavy snow, and were very useful in clearing the lines. After rescuing Henry from a snowdrift, the engines all sided with the twins and complained it wasn't fair that one of the engines should be sent back. The engines decided to appoint a deputation, who turned out to be Percy, to speak to the Fat Controller about the issue. Percy successfully persuaded him to change his mind, and Donald and Douglas now usually work all over the island, though mainly on the Wellsworth and Arlebourgh Branch Lines.

In the deep freeze of January 2014, the twins were sent to dig out the village of Ulfstead from the snow. Unfortunately, the ran into a massive snowdrift on the way, and got stuck. The snow turned into ice and was nearly impossible to remove, as James and Toby found out. They were stuck overnight. The next morning, they were freed when the workmen lighted gasoline on the ice. Unfortunately, this melted their wheels, and they had to get them mended. Later that year when D199 came back to Sodor, the twins were very unwelcoming, and gave him the cold shoulder. When they had to work with him on the flour mill line, they were very cross, and the three got on terribly. This was until D199 saved them from a falling bridge which caused him to fall into the water. The twins felt terrible, and made amends with D199, now Ted, after he was mended.

Trainz ModelsEdit

SI3D's 2010 models of Donald and Douglas were used until An Unfortunate Coincidence for Jock. From then onwards, Sodor Workshops's model's are used.


Donald and Douglas are based off of the 812 "McIntosh" 0-6-0s from the Caledonian Railway in Scotland.


The Scottish Twins are very proud of their Scottish heritage, and take no nonsense. They are fairly optimistic though they can get easily irritated (mainly Donald). Occasionally they argue with each other, and had a big fallout in 2002, but this is extremely rare. Though both work better when independent than engines like Bill and Ben, they do have a bond that cannot be broken.

Douglas in the TV Series


  • Donald and Douglas were the first engines in the RWS and TV show to have an accent other than English.
  • Donald and Douglas were painted blue in the Railway Series shortly after arriving to the North Western Railway, whilst they have always remained black in the TV show. This is likely to differentiate them from other blue engines such as Edward, Gordon, and Thomas.
