Jinty and Pug are two LMS tank engines from the Other Railway.
They are friends of Percy.
They were borrowed from British Railways to run the North Western Railway while Sir Topham Hatt's engines visited the mainland. Jinty ran Thomas' Branch Line while Thomas was away and also helped Thomas when the latter 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".
Jinty and Pug are painted in British Railways unlined black livery. Jinty has the BR logo painted on his side tanks.
