“Said Harold Helicopter to our Percy, 'You are slow. Your railway is out of date, and not much use you know.' But Percy with his stone trucks did the trip in record time, and we beat the helicopter on our old branch line!”
―Percy's fireman singing the victory song

Percy and Harold, retitled Percy Proves a Point in American releases, is the ninth episode of the second series. It is based on the story of the same name from the Railway Series book Percy the Small Engine.


Percy is now working at the new harbour on Thomas' Branch Line. He often has to fetch trucks, and although he works hard, he still likes his new job and prefers branch line work over shunting for the mainline engines at the big station. Along the branch line is an airfield and Percy hears the planes flying overhead. The loudest, though, is a helicopter, the noise of which Percy ends up complaining about.

One day, Percy stops with his train at the airfield to talk to the helicopter, whose name is Harold. Percy compliments Harold for his big, strong arms and Harold responds that he thinks railways are slow and out of date. When they finish, Harold flies away and Percy sets off for the quarry. Percy finds Toby and expresses his feelings about Harold. Afterwards, he collects his trucks and heads back to the harbour.

On Percy's trip back to the harbour, they hear Harold's unmistakable buzzing overhead. Percy's crew encourage him to race with the helicopter, which Percy has never been allowed to do before and is excited. The trucks wail and beg Percy to stop, but it is no use. The fireman shovels for dear life as Percy rockets down the line. They have to slow down when they reach the wharf and see a distant signal, Percy is sure that they have lost the race. But when his fireman climbs onto the roof of the cab, he realises they have won, as he can see Harold still hovering and looking for a place to land.

In celebration of Percy's victory, the fireman sings a song about the race which Percy loves, especially the last line.
