Thomas the Tank Engine
Thomas's on-screen appearances in the TV series were developed by Britt Allcroft. The first series of 26 stories premiered in October 1984 on the ITV Network in the UK, with former Beatles drummer/vocalist Ringo Starr as storyteller. The stories were featured as segments as part of Shining Time Station in the US beginning in 1989 with Starr as the show's Mr. Conductor character. From 1991 to 1993, George Carlin replaced Starr as both the storyteller and as Mr. Conductor for Shining Time Station. Carlin also told the Thomas stories for Shining Time Station in 1995.
Bertie the Bus
Bertie first appeared in "Thomas, Terence and the Snow", a story in "Tank Engine Thomas Again" (published 1949). His first major appearance came in the next story, 'Thomas and Bertie', where he had his famous race with Thomas. The story proved to be very popular, which ensured that Bertie would return. He did eventually return, in Edward the Blue Engine, becoming the only non-rail character to appear in more than one book by the Reverend Awdry. He made one final appearance in More About Thomas the Tank Engine (published in 1986), by Christopher Awdry, though has had numerous mentions under Christopher's name.
