Residents worried about plans to build hundreds of homes on railway sidings say building on the land could cause a disaster CAMPAIGNERS fighting a bid to build hundreds of homes on a former railway sidings site, say if the plan went ahead it could cause a 'disaster' of contamination and flooding. Developer One Swindon has lodged an application to build 368 flats and houses on land running alongside the railway line between Rodbourne Road and Wootton Bassett Road. But nearby residents say the site is simply not suitable. A leaflet produced by them, called Sidings Objector, says: “The site is built up ground to take the rail line over the Wootton Bassett Road Bridge. A range of waste railway materials are buried below the porous permanent way ground cover.
