a major change in British rail travel. When the so-called Derby Lightweights were produced they were each tested on the line after leaving the workshop. One of the only three surviving of those originally built, M79900, was converted from being the IRIS test car back to passenger carrying standard and has been joined recently by the other two, residing on the line on which they were originally tested some 60 years ago. Rail accident On 25 August 1981, a rail accident occurred when a fully laden freight train partially derailed south of Wirksworth. Decline and closure Although most of the goods had transferred to the roads, limestone traffic continued, including that formerly hauled by the Cromford and High Peak Railway, when it closed in 1967. Though the amount of traffic justified the installation of some continuous welded rail in the 1980s, production was increasingly of aggregate carried by road. In 1991 the quarries passed to Croxton and Garry Ltd (which later became Omya UK) which no longer needed a rail link. Although its sidings, and the station goods yard, at Wirksworth are still listed by Network Rail, the connection to the main line at Duffield has been severed and fenced off, There is hope that one day the EVR could "once possible funding would be made" purchase and re-use both the goods yard and the sidings for further/extra space for some rolling stock and train storage. Present day Preservation In 1996 WyvernRail were awarded a Light Railway Order for the full length of the whole line. Wirksworth station was reopened in 2002, with the first of line between and Gorsey Bank reopened for a DMU shuttle passenger service in 2004, followed by a new line to in 2005. On 8 March 2008, the railway began to branch its passenger operations further south by holding a grand opening ceremony for the line between Wirksworth station and Idridgehay station – of the line's total length. In 2003, WyvernRail agreed a 15-year lease-purchase deal with Network Rail. In May 2005, they completed the purchase early and bought almost the entire railway. The only portion still leased is an area of the station yard in Wirksworth which has been retained by Network Rail as a Strategic Rail Site and is on a rolling three-year lease to WyvernRail. In July 2005, WyvernRail adopted Duffield railway station under a scheme promoted by the Friends of the
