Harold

"Stupid thing. Why can't it go and buzz somewhere else?"

- Percy, Percy the Small Engine

  Harold Harold is a helicopter who patrols the Island looking for problems.

Bio
When Harold first met Percy, he stated that railways were "slow and out-of-date", but was proven wrong when Percy beat him in a race. When Thomas' brakes failed while boarding at a station, with an inspector Harold chased him down the line. Christmas that year Harold brought Santa Claus to the party at Tidmouth Station. Harold also dropped hot drinks for Percy's crew when they were stranded in a floating river and made friends with Duck after rescuing an injured sailor.

Harold lives at Toryreck airfield (Dryaw in the television series) by Thomas' Branch Line. He keeps a watchful eye over Sodor in case of trouble and speeds to the rescue of anyone in distress.

As of Misty Island Rescue, he has joined the Sodor Search and Rescue team and lives in his own hangar at the Sodor Search and Rescue Centre. Since joining the team he has been involved in a search for Thomas when he got lost, saving Bertie from the Shake Shake Bridge and helping to recapture an escaped elephant. Once, Harold's rotors became jammed, so Thomas and Duck took him to the Sodor Search and Rescue Centre. After this, he helped Charlie find an elephant which had escaped from the Sodor Animal Park, and then Charlie took it back.

Persona
Harold speaks in a manner reminiscent of an RAF pilot, using terms such as "wizard" and "old chap" in conversation.

Harold somewhat tends to be full of himself as he feels that "railways are slow", but he always gets his comeuppance in the end.

Basis
Harold is based on a Sikorsky S-55 helicopter, built in the UK as the Westland Whirlwind. He has added floats.

Livery
Harold is painted white with red lining.
