Wooden toy train
"Thomas the Tank Engine" is a character created by the Rev. W. Awdry in "The Railway Series" of children's books, first published in the U.K. in 1945. In 1984 a television series called "Thomas the Tank Engine and Friends" was made, adding to the popularity of the characters. It was first broadcast in the United States in 1989. John W. Lee founded the company "Learning Curve Toys" in November 1992 with a wooden railway system called "Thomas & Friends" based on the Thomas the Tank Engine characters. This made the wooden toy trains even more popular than before. Learning Curve introduced some new designs for the track surface, such as the "Clickety Clack" rails patented 1995 and the newer tracks in 2002 with a relief to supply better traction grip for battery powered four wheel drive trains patented in 1998.
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.
