<Tr> <Th> Sights </Th> <Td> Otago Central landscape, railway viaducts </Td> </Tr> <P> The Otago Central Rail Trail is a 150 - kilometre walking, cycling and horse riding track in the South Island of New Zealand . A pioneering project for New Zealand, the successful cycle trail joined the New Zealand Cycle Trail umbrella organisation in 2012, having been one of the inspirations for it . </P> <P> The trail runs in an arc between Middlemarch and Clyde, along the route of the former Otago Central Railway . The trail has become a popular tourist attraction, with 10,000 - 12,000 users per year as a conservative estimate, and yearly (and ongoing) user increases for 6 out of the last 7 years (as of 2011). The trail is also accepted as being, by a large margin, the biggest non-farming economic factor in the Maniototo - Alexandra area . </P> <P> The original railway line was completed at the turn of the 20th century, and provided a link between Central Otago and Dunedin until closure in 1990 . The first 64 km from the junction with the Main South Line in Wingatui remain operational; the initial 4 km form KiwiRail's Taieri Industrial Siding and the remaining 60 km through the Taieri Gorge to Middlemarch is operated by Dunedin Railways as a tourist attraction . The New Zealand Department of Conservation recognised that the remainder of the route to Clyde had potential as a recreational facility, and bought the formation after the rails and sleepers had been salvaged . </P>
