Raurimu Spiral
The Raurimu Spiral is a single-track railway spiral, starting with a horseshoe curve, overcoming a height difference, in the central North Island of New Zealand, on the North Island Main Trunk railway (NIMT) between Wellington and Auckland. It is a notable feat of civil engineering, having been called an "engineering masterpiece." The Institute of Professional Engineers of New Zealand has designated the spiral as a significant engineering heritage site. Background During the construction of the central section of the NIMT, a major obstacle arose: how to cross the steep slopes between the North Island Volcanic Plateau to the east and the valleys and gorges of the Whanganui River to the west? South of Taumarunui, the terrain is steep but not unmanageable, with the exception of the stretch between Raurimu and National Park, where the land rises too steeply for a direct rail route. A direct line between these two points would rise in a distance of some , a gradient of 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiral (railway)
A spiral (sometimes called a spiral loop or just loop) is a technique employed by railways to ascend steep hills. A railway spiral rises on a steady curve until it has completed a loop, passing over itself as it gains height, allowing the railway to gain vertical elevation in a relatively short horizontal distance. It is an alternative to a zig-zag, and avoids the need for the trains to stop and reverse direction while ascending. If the train is longer than the length of each loop it may be possible to view it looping above itself. The term "loop" is also often used for a railway that curves sharply and goes back on itself: if the railway crosses itself, then it forms a spiral or helix; otherwise, it forms the much more common horseshoe curve or bend.

National Park, New Zealand
National Park is a small town on the North Island Central Plateau in New Zealand. Also known as National Park Village, it is the highest urban township in New Zealand, at 825 metres. Its name derives from its location just outside the boundary of Tongariro National Park, New Zealand's first national park, and its only national park from its creation in 1887 until 1900. The village has great views of Mount Tongariro, Mount Ngauruhoe (Mount Doom in the ''Lord of the Rings'' film trilogy), and Mount Ruapehu. The town is sited next to the North Island Main Trunk railway line and close to the junction of State Highways 4 and 47, halfway between Raetihi and Taumarunui and 45 kilometres southwest of the southern shore of Lake Taupō. It is 20 minutes drive to the country's biggest skifields, Whakapapa and 50 minutes drive to Turoa on the slopes of the active volcano, Mount Ruapehu. To the west is Whanganui National Park. The town is administered by the Ruapehu District Counc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heritage New Zealand Pouhere Taonga (initially the National Historic Places Trust and then, from 1963 to 2014, the New Zealand Historic Places Trust) ( mi, Pouhere Taonga) is a Crown entity with a membership of around 20,000 people that advocates for the protection of ancestral sites and heritage buildings in New Zealand. It was set up through the Historic Places Act 1954 with a mission to "...promote the identification, protection, preservation and conservation of the historical and cultural heritage of New Zealand" and is an autonomous Crown entity. Its current enabling legislation is the Heritage New Zealand Pouhere Taonga Act 2014.

Buildings And Structures In Manawatū-Whanganui
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tehachapi Loop
The Tehachapi Loop is a long spiral, or helix, on the Union Pacific Railroad Mojave Subdivision through Tehachapi Pass, of the Tehachapi Mountains in Kern County, south-central California. The line connects Bakersfield and the San Joaquin Valley to Mojave in the Mojave Desert. Rising at a steady two-percent grade, the track gains in elevation and makes a diameter circle. Any train that is at least 3,800 feet (1,162 m) (approx. 56 60’(67'11") box cars) long passes over itself going around the loop. At the bottom of the loop, the track passes through Tunnel 9, the ninth tunnel built as the railroad was extended from Bakersfield. The line averages about 36 freight trains each day; passenger services such as Amtrak's ''San Joaquin (Amtrak), San Joaquin'' are banned from using the loop, while the ''Coast Starlight'' can only use it as a detour. Its frequent trains and scenic setting make the Tehachapi Loop popular with railfans. In 1998, it was named a National Historic Civ ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Raurimu Railway Station
Raurimu railway station was a station on the North Island Main Trunk, and in the Manawatū-Whanganui region. It opened in 1906 and closed in 1978. It was known as Pukerimu from 1906 to 1908. The Raurimu Spiral is from the station, and rises to the National Park railway station on the North Island Volcanic Plateau; on a direct line this would be a gradient of 1 in 24, but the Raurimu Spiral reduces the gradient to a (still steep) 1 in 52. History In 1906 the administrative office of the northern section of the Public Works Department (PWD) which was building the NIMT was moved to a group of "tents and huts" at Raurimu, and at its zenith the Raurimu community numbered a thousand men, women and children. Trains started running to Raurimu from 13 December 1906. From 10 May 1907 goods were carried to Raurimu by rail. Trains started running to the next station at Waimarino (National Park) from 23 December 1907. The NIMT was opened to through Auckland to Wellington trains from 9 N ...
