Percy

Bio
Percy ran Thomas' branch line while Thomas ran the mainline with Edward, and was allowed to stay after the big engines surrendered. At first, Percy liked to annoy the big engines. Percy was later waiting at Tidmouth but forgot to whistle to the signalman, and thus was startled when Gordon came running towards him with the Express. Gordon managed to stop in time, but Percy was frightened, ran away, and ended up in a sandbank. He was rescued by Gordon, and took up the duty of station pilot at Tidmouth.

Percy was still a cheeky engine and often liked to play jokes on Gordon and James, but one day the other engines got their revenge when Percy failed to recognise a "backing signal". After this, Percy was subject to bullying from the big engines until Duck arrived and helped Percy to put the big engines in their place.

With Duck's arrival, Percy was sent to Knapford to help build the harbour, and has stayed there ever since as a goods engine.

Persona
As the television series has progressed, Percy has been dumbed down in order to teach viewers difficult words: he would say "dingy-fried" where anyone else would say "dignified". He also is shown to make obvious mistakes.

Percy is incredibly accident-prone, and holds the dubious record of the most accidents in one season - five, in the second season - crashing into some buffers, falling into the sea, being pushed onto a brakevan, colliding with a cart and being hit by a falling crate of treacle. So far, his silliest accident yet was in the sixth season, when he slipped on oily rails, crashed through the chocolate factory and emerged covered in chocolate.

Basis
Percy is primarily based on an Avonside 0-4-0ST with the body of a GWR 1340 Trojan, the bunker of a GWR 1361, Hunslet underframes and valve gear, a smokebox protruding from his saddletank, external cylinders and motion and sandboxes underneath the tanks on the footplate.

Modifications made to Percy's shape are needed the angled smokebox supports and the cab being cut down slightly from the back for the bunker.

Livery
Percy is painted NWR green with NWR red-and-yellow lining and a "6" painted on his bunker sides in yellow.
