Wiesen Viaduct
The Wiesen Viaduct (or Wiesener Viaduct; german: Wiesener Viadukt) is a single-track railway viaduct, made from concrete blocks with dimension stone coverage. It spans the Landwasser southwest of the hamlet of Wiesen, in the canton of Grisons, Switzerland. Designed by the then chief engineer of the Rhaetian Railway, Henning Friedrich, it was built between 1906 and 1909 by the contractor G. Marasi (Westermann & Cie, Zürich) under the supervision of P. Salaz and Hans Studer (RhB). The Rhaetian Railway still owns and uses it today for regular service. An important element of the Davos–Filisur railway, the viaduct is high and long; it has a main span of . Location The Wiesen Viaduct forms part of the Davos–Filisur railway section between Wiesen and Filisur. Just southwest of Wiesen railway station, it has, on its south side, a separate pedestrian bridge giving hikers access to Filisur. At the western end of the viaduct is a non functioning Hippsche turning wheel. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Train
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not. A push–pull train has a locomotive at one end of the train, connected via some form of remote control, such as multiple-unit train control, to a vehicle equipped with a control cab at the other end of the train. This second vehicle may be another locomotive, or an unpowered control car. In the UK and some other parts of Europe, the control car is referred to as a ''driving trailer'' (or driving van trailer/DVT where there is no passenger accommodation); in the US and Canada, they are called ''cab cars''. Train formation Locomotive at one end Historically, push–pull trains with steam power provided the driver with basic controls at the cab end along with a bell or other signalling code system to communicate with the fireman located in the engine itself in order to pass commands to adjust controls n ...

Hipp Reversible Disk Signal
The ''hippsche Wendescheibe'' or '' Hipp’sche Wendescheibe '', is a historical railway signal. The automatic and visual signal served as distant signals and home signals. Its main advantage was that energy to move the signal was provided locally, while the low power impulse to move the signal was transmitted electrically from the signal box, thus minimizing cumbersome and unreliable energy transmission over distance. Description History This type of signal was developed by the inventor and watchmaker Matthäus Hipp and first used in Winterthur in 1862. The signal is named after him and was in use long before the wing signals. How it works The Hipp reversible disc signal is mounted on a hollow cast column. This carries a sheet metal disc about 1m in diameter. Until 1877 the disc was painted red on both sides with a white border, but later on one face red with a white diagonal bar and on the reverse white and black, partly chequered, partly with a diagonal bar, or simply paint ...

Bridges Completed In 1909
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Graubünden
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 artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhaetian Railway Bridges
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma (million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise age dat ...

Viaducts In Switzerland
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernina Express
The Bernina Express is a train connecting Chur (or Davos) in Switzerland to Poschiavo in Switzerland and Tirano in Italy by crossing the Swiss Engadin Alps. For most of its journey, the train also runs along the World Heritage Site known as the Rhaetian Railway in the Albula / Bernina Landscapes. The train is operated by the Rhaetian Railway company for the purpose of sightseeing. It takes the form of an enhanced regional service between Tirano and Chur or Davos: panoramic coaches with enlarged windows and multi-lingual (English, Italian and German) audio guide on board. It is not an "express" in the sense of being a high-speed train; passengers must make a seat reservation either directly when they purchase Bernina Express tickets, or pay a small supplement on top of their regional train tickets. The Bernina Express is popular with tourists and connects in Tirano with the Post Bus service via Lake Como in Italy to Lugano in Switzerland. The Albula line and the Bernina l ...

Rhaetian Railway Ge 4/4 I
The Rhaetian Railway Ge 4/4 I is a class of metre gauge Bo′Bo′ electric locomotives operated by the Rhaetian Railway (RhB), which is the main railway network in the Canton of Graubünden, Switzerland. The class is so named because it was the first class of locomotives of the Swiss locomotive and railcar classification type Ge 4/4 to be acquired by the Rhaetian Railway. According to that type designation, ''Ge 4/4'' denotes a narrow gauge electric adhesion locomotive with a total of four axles, all of which are drive axles. The 10 machines in the Ge 4/4 I class were also the first RhB electric locomotives without rod drive. History In 1944, the Rhaetian Railway ordered four Ge 4/4 I class locomotives from the Swiss Locomotive and Machine Works (SLM). The first of these machines was commissioned in July 1947. In service primarily in the haulage of fast trains, they proved themselves so well that in 1953 the Rhaetian Railway order ...

List Of Longest Masonry Arch Bridge Spans
The masonry arch bridges of stone or brick are the most genuine of arch bridges, some lasting a thousand years. Because they are made of worked stone, there is a slight chance they might even stand without mortar, like the Pont du Gard aqueduct. Yet arch bridges using rough hewn stones like Changhong Bridge need mortar to stand. Arches with a core of reinforced concrete covered by facade stone for decoration are not to be included in this list, the load-bearing part of the arch should be cut stone or brick, or as follows, ''un''reinforced concrete. In a closed spandrel stone arch bridge the hollow space can be filled with rubble and loose material. It can also be filled with concrete, in which case the filling itself become able to bear load in addition to the load carried by the ring of voussoirs. If the voussoir stones are thin they can not take a lot of weight so instead it is the concrete filling that becomes the structural part of the arch. The next step is to remove the vouss ...

Ernst Ludwig Kirchner
Ernst Ludwig Kirchner (6 May 1880 – 15 June 1938) was a German expressionist painter and printmaker and one of the founders of the artists group Die Brücke or "The Bridge", a key group leading to the foundation of Expressionism in 20th-century art. He volunteered for army service in the First World War, but soon suffered a breakdown and was discharged. His work was branded as "degenerate" by the Nazis in 1933, and in 1937 more than 600 of his works were sold or destroyed."Ernst Ludwig Kirchner: German, 1880–1938" . |
