Track, and at Mickleover in Derby and The High Marnham Test Track, the former LD&ECR from Shirebrook to Tuxford where one of Network Rail's RIDC is located. RTC today At privatisation, most of the facilities were taken over by commercial railway engineering companies, and it was marketed as the "rtc Business Park" renting space to a range of small consultancy firms. The only facility which is still used for railway research is the moving-model aerodynamic test facility. The former RTC site is used by Loram to carry out repairs and maintenance on railway vehicles. It was also used by Rampart Carriage & Wagon Services (RC&WS) which went into liquidation in 2013. A large part of the site is used as storage and an operating base by Loram and Network Rail, whose rolling stock on site forms part of Network Rail testing trains. Usual traction on these trains is either Colas Rail class 37s or class 67s. The New Measurement Train and Loram C21 Grinding/Rail Profile Trains are also maintained at this facility. LCR (London and Continental Railways) took over the site in 2013 in response to a demand from the local community to retain RTC’s position as a key employment site and preserve its status as a core asset for Derby’s internationally-acclaimed engineering business cluster References General references British Railway Research 1864-1965 by S.Wise,C.Eng.,F.I.Mech.E.,M.I.M.
