|Donald and Douglas|
9 & 10
The Lorries - Donald
Escape - Douglas
Donald and Douglas are practical and level-minded characters who nevertheless enjoy a joke, especially impersonating one another - the fitting of the twins with nameplates was done to specifically end this element of their humour. Their tendency for jokes, however, has continued and both display a keen sense of wit and, where necessary, an acid tongue. In their work, however, their performance is exemplary and they can be described as some of the most well-regarded engines in service on the railway, comparable with Duck and Edward in their reliability.
Donald and Douglas are Caledonian Railway 812s.
