Description: Lord Palumbo of Walbrook opened it on Monday, 23rd June 1997. It is modeled on the 1938 record setting, 126mph steam locomotive "Mallard". The project was headed by sculptor David Mach and is said to have cost around £760,000 in total. It was funded by the National Lottery, Wm Morrison Supermarkets, Northern Arts, Department of National Heritage, Darlington Borough Council and sponsorship in kind. A total of 185,000 bricks were used in its construction along with 170 cubic meters of concrete. The train weighs 15,000 tonnes and covers an area of 600sq meters. It is of hollow construction and measures 23ft high by 130ft long. A team of 34 brickies, labourers and apprentices actually built it in 21 weeks. There are 20 special 'bat' bricks built in at various places to encourage the nocturnal creatures to use it as their home. Some of the local schools have also donated 'time capsules' which have been put inside the train.
