Thomas the Tank Engine & Friends

Percy & the Signal (2x7)

Air date: Sep 17, 1986

Percy has been playing tricks on the bigger engines, such as telling Gordon he is late for his train and telling James he mustn't leave the shed because an Inspector is coming to visit. Gordon and James want their revenge, and so come up with a plan to trick Percy, by brainwashing him with the ludicrous idea of "backing signals"...
