AN important part of the region's railway heritage could be jeopardised if land is sold to a property developer.

The Grade II*-listed Stephenson Engine Works, in South Street, behind Newcastle Central Station, was part of a factory complex that produced pioneering locomotives in the 1820s.

Robert Stephenson became managing director of what was the first purpose-built locomotive factory in the world, when he was 19.

The site is owned by the St Mary the Virgin estate management charity, a Newcastle-based body set up in the 12th Century that provides sheltered housing. The charity wants to sell off 7.5 acres - including the factory - in a deal worth about £4m.

The Stephenson Trust pays £5,400 a year rent for the factory and its leaders fear that a new landowner could raise the tariff, pricing them out of the market.

Trust chairman Bob Longridge said: "There is some concern on our part. We are keeping a watching brief and asking to be kept informed of developments."

Earlier this year, Newcastle City Council unveiled plans to transform the area.

Dubbed the Stephenson Quarter, its revitalisation has already started with the award-wining Central Square development and the conversion of the Turnbull building into luxury apartments.

Bids for the land are due in by October 31.
