Harold

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

- Percy, Percy the Small Engine

  Harold Harold is a helicopter used for patrolling the Island.

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When Harold first met Percy, he stated that railways were "slow and out-of-date", but was proven wrong when Percy beat him in a race.

Harold is owned by the coastguard on Sodor and lives at Dryaw airfield 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 Rescue Centre.

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 often feels that "Railway's Are Slow", but of course 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.
