saw a grand reopening on 24 May 1997, was leased to a model shop and buffet, and the Dartmoor Railway began operation in 1997 with a fleet of historic locomotives, coaches, and diesel and electric multiple units, including classes 08, 47, 117, 205, 411, 421 and 438. Steam-hauled charter services also visited occasionally. RMS Locotec was contracted to maintain the line and rolling stock. Meldon Viaduct, an iron truss bridge about further up the line from Okehampton, was designated as a scheduled monument and refurbished shortly after the opening of the heritage railway; a new station of the same name, unrelated to any historic station, was built at its eastern end in 2000 for the heritage railway. The track across the viaduct was lifted in 1990 as the structure was assessed to be too weak to take the weight of a train. In September 2008, British American Railway Services Ltd, a company created by Iowa Pacific Holdings of Chicago, became the new owner of the Dartmoor Railway community interest company. The company announced its intention to develop freight, passenger and tourist services on the railway. Heritage services ran between Okehampton and Meldon Viaduct, extended to Sampford Courtenay, Bow or the Dartmoor Railway–Network Rail boundary on special event days. The former stations at North Tawton and Bow remain closed to passengers: both are privately-owned and have no public access. Themed trains were introduced for special occasions such as Christmas, with names like The Polar Express and The Train to Christmas Town. The quarry at Meldon was mothballed in 2011, bringing an end to stone freight trains using the line. Heritage train services ceased in December 2019 and, in February 2020, the railway entered administration. Rolling stock based at Okehampton station was moved to Meldon Quarry, with most offered for resale. Public train services After the heritage Dartmoor Railway opened in 1997, First Great Western operated a summer Sunday service of four return trips direct from Exeter between May and September, sponsored by Devon County Council. These trains connected with bus services and heritage railway services at Okehampton, Tarka Line rail services at and other national rail services at Exeter. Devon and Cornwall Railways (a subsidiary of British American Railway Services) announced its intention to operate through services from Okehampton to Exeter in 2010, having made a track access application to Network Rail on 18 March 2010 to operate four return services
