from the end of February to December, and on Wednesdays and Thursdays in summer. There are also various special events throughout the year. Guest steam locomotives Although predominantly diesel-operated, the MNR is not a diesel-only railway. The first train from after preservation, running between Dereham and Yaxham, was hauled by Manning Wardle tank locomotive "Sir Berkeley", and the railway has always intended to operate both steam and diesel trains. In 2000, the railway arranged the loan of Barclay 'Little Barford'. Although the locomotive was too small to operate a scheduled service over the line it was used for a number of crew training runs, and, on Monday 12 June 2000, it became the first steam locomotive in preservation to operate over the entire route between Dereham and Wymondham. Steam also visited the line, although not to operate services, in 2001 when LNER Thompson Class B1 61264 was routed via Dereham for repairs after failing on railtour at Norwich, 20 November. The 2006 return of steam-hauled passenger services marked the completion of Dereham Station restoration and the installation of steam infrastructure (such as the water tower). The first locomotive to haul timetabled steam services over the Dereham to Wymondham section since 1955 was GWR 9400 Class 9466. The same locomotive returned to operate the line's steam services in June and July 2007, although Battle of Britain class 34067 Tangmere also visited this year, operating some scheduled trains and hauling the first steam charter from Dereham (to London Liverpool Street), on 5 May. Steam services have continued to operate during summer months. Network Rail connections Commercial freight Mid-Norfolk Railway facilitates commercial freight trains, using its connection with the National Rail network at Wymondham. Dereham yard has been used as a servicing depot by Direct Rail Services since 2007 and for storage of Network Rail track plant since 2008. The road vehicle loading ramp in Dereham yard is used by mainline train operators to load damaged rolling stock onto road vehicles. Such rolling stock usually comes at night (via the connection with the mainline at Wymondham) at slow speed (sometimes on wheelskates) from Crown Point TMD in Norwich (where no road-rail loading facilities are available) for onward road movement to specialist repair facilities around the country. The line has also been used to carry equipment for army units based at Robertson Barracks or undergoing training at the Stanford Training Area, most recently in
