“Said Harold Helicopter to our Percy, 'You are slow! Your railway is out of date, and not much use you know!' But Percy and 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 season. In the US, it aired on the Shining Time Station episodes Just Wild about Harry's Workshop in 1989 and Field Day in 1991.


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 rather than shunting for the mainline engines at the big station. Along the branch line is an airfield and Percy would hear the planes flying overhead. The loudest though is a helicopter. Percy complains about the noise it would make.

One day Percy stops with his train at the airfield. The helicopter is there and they begin by introducing each other. The helicopter's name is Harold and it is not long before the two start trading insults. When they finish, Harold flies away and Percy sets off for the quarry. Percy finds Toby and vented off 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. Percy's crew encourage the two to race each other. Percy has never been allowed to go that fast before. The trucks wailed and beg Percy to stop, but it is no use. They have to slow down when they reach the wharf and Percy is sure that they had lost the race. But when the fireman climbs onto the roof of the cab, he can see Harold still 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.
