The Railway Series
In 1956, they were borrowed from British Railways to run the North Western Railway while Sir Topham Hatt's engines visited the Mainland. Jinty ran on Thomas' Branch Line while Thomas was away and also helped the latter when Thomas had crashed into some buffers.
Jinty is based on an LMS 3F 0-6-0T. Pug is based on an LMS 0F Kitson 0-4-0ST. Their names originate from their classes' nicknames "Jinty" and "Pug". A total of nine 3F 0-6-0 tank engines survive in preservation whereas sadly, all ten 0F Kitsons were scrapped.
Jinty and Pug are painted in BR unlined black. Jinty has the BR logo painted on his side tanks. It is possible that Pug has a BR logo on his cab, though the Water Tower obscures it.
Not much is know about Jinty and Pug's personalities, but they seem to be friendly and polite engines, seeing as they said hello to Percy upon arrival and Jinty was willing to help Thomas after his accident.
- In the second illustration of The Fat Controller's Engines, Jinty and Pug are not illustrated with faces.
- Jinty's role in the fourth series episode, Thomas and the Special Letter was replaced with Oliver.
