Delete the Mixed-Traffic Engine is a spin-off series focusing on Delete. The two seasons are split into two 'volumes'. (See below for titles). The first season takes place in late 1947 to early/mid-1948, and 1953. The second season takes place from 1955-1968.


Plans for Delete's own series had been alive since the character was created. But, of course the engine just needed a basis. The LNER Thompson Class B1 'Oliver Bury' was chosen as Delete's basis. On July 24th, the episode 'Delete' aired which explained Delete's backstory, about his life on the BR. The seventeen episodes that followed, were all memorable adventures for Delete. Mentioned in 'Delete', a leak of steam started to take affect four years after he arrived on Sodor. He was repaired, and got to go to the Mystic River Traction Company Railway. A second season had also been planned, which was confirmed on August 13th, 2012. It was to have 23 episodes. Nineteen episodes have been confirmed, and will start airing September 13th, after the eighth season. However, it has been confirmed that the second volume/season will have twenty episodes, like the first.
