"We had spoken of backing signals. They need extra special care, you know. Would you like me to explain?"
"No thank you, James. I know all about signals!
— James and Percy

Percy and the Signal is the seventh episode of the second season.


Percy works in the yard at the big station, collecting coaches and trucks that the bigger engines need for their trains. Although he works hard, he can also be very cheeky. First, he wakes Gordon up by telling him is train is ready. Gordon jumps, thinking he is running late, only for Percy to reveal a line of dirty trucks. Gordon is angry and tries to think of a way to pay Percy back.

Percy then goes to James and tells him that the Fat Controller has sent a message for James to not leave the shed. James is delighted, thinking the Fat Controller wants him to pull a special. As a result, he refuses to leave the shed when his driver and fireman try to take him out. The other engines are angry over having to do James' work as well as their own. Finally an engine inspector arrives and tells James to move. James refuses and tells him about the message the Fat Controller sent. The inspector points out the Fat Controller could not send a message as he is away. James is horrified and quickly leaves to find Percy, but Percy had decided to make himself scarce. When the Fat Controller gets back, he does speak to James as well as Percy, telling them both off for causing trouble.

A few days later, Percy is showing off to Gordon and James as the Fat Controller has asked him to take trucks to Thomas' junction. He is boasting that he was chosen as he is a really useful engine. James remarks that the Fat Controller probably wants Percy out of the way. Gordon and James then put form a plan and put it into action. They claim they were talking about being careful with the signals at the junction, especially "backing signals". Percy, keen to show off, claims that he knows all about signals and leaves, but worries as he has never seen or heard of a backing signal before. However, he decides not to dwell on it and collects his trucks before traveling to the junction.

Soon Percy arrives at a signal set to danger. However, when it moves to show the line is clear, the arm moves up instead of down. Percy, having never seen this kind of signal before, guesses that it is a backing signal and begins reversing. Percy's driver is shocked and quickly stops him, but Percy protests that it is a backing signal and tells his driver about what Gordon and James had said. The driver is amused and tells Percy the truth. Percy is eager to leave before he is seen, but it is too late. Gordon sails past having seen the whole incident. Embarrassed, Percy quickly and quietly finishes his work.

That night in the sheds, Gordon and James talk about nothing but signals. While they think it is funny, Percy is less than impressed.
