Thomas and Friends
The first attempt to adapt Awdry's stories for television came in 1953, when the editor of the Railway Series books, Eric Marriott, was approached by the BBC, who wished to use live-action model trains to re-create two stories from Awdry's first book, The Three Railway Engines. 00 gauge Hornby Dublo models appeared on sets that reflected the style of the original illustrations. The first episode (based on "The Sad Story of Henry") was broadcast live on the evening of Sunday 14 June 1953 from Lime Grove Studios. The live broadcast did not fare well: a failure to switch the points caused the model of Henry to derail and it had to be replaced on the rails by one of the operators. The models moved jerkily, and all effects and music had to be superimposed.
