Gryph is a state-of-the-art electric rescue train who can travel at over 1000 kilometres per hour. He is constructed from a secret alloy called 'endurium' which is bullet-proof and can convert sunlight into electricity to recharge his batteries. His advanced computers allow him to think for himself and communicate with humans. He is owned by the government and is stationed in the centre of the country; he can reach any scene of disaster or accident, on or near the railway, anywhere in the land, within hours. He is equipped with the latest machines - robot cranes, bulldozers/diggers, a helicopter and a micro submarine - that can communicate with humans and can act independently. Gryph communicates with his headquarters (Headshed) via satellite. He has two drivers, Sally Forth and Jet Stream, who take it in turn to drive him or command the rescue at the scene. There is a crew of over one hundred on board who are fully equipped engineers, scientists, technicians, doctors, nurses and chefs, all dedicated to saving people and animals whose lives are in danger.
