Montenvers Railway
The Montenvers Railway or Chemin de fer du Montenvers is a rack railway line in the Haute-Savoie department of France. The line runs from a connection with the SNCF, in Chamonix, to the ''Hotel de Montenvers'' station, at the Mer de Glace, at an altitude of . Overview The line is long and has a track gauge of . It is a rack and adhesion railway, using the Strub rack system to overcome a height difference of . Except for the terminal stations, which are operated in adhesion mode, the line has a gradient varying from 11% to 22%. The line is operated by the which also manages the Mont Blanc Tramway and many ski lifts in the Mont Blanc region. The first section of the line as far as Caillet opened in 1908 and the line was completed in 1909. The trains originally were drawn by steam locomotives built by SLM who supplied six 2-4-2T locomotives between 1908 and 1923. By 1953 the line was electrified, using an overhead line at 11 kV AC and 50 Hz, and service is provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mer De Glace
The Mer de Glace ("Sea of Ice") is a valley glacier located on the northern slopes of the Mont Blanc massif, in the French Alps. It is 7.5 km long and deep but, when all its tributary glaciers are taken into account, it can be regarded as the longest and largest glacier in France, and the second longest in the Alps after the Aletsch Glacier. Geography The glacier lies above the Chamonix valley. The pressure within the ice is known to reach at least 30 atmospheres. The Mer de Glace can be considered as originating at an elevation of , just north of the Aiguille du Tacul, where it is formed by the confluence of the Glacier de Leschaux and the Glacier du Tacul. The former is fed by the Glacier du Talefre, whilst the latter is, in turn, fed by the Glacier des Periardes, the vast Glacier du Géant and the broad icefields of the Vallee Blanche. The Glacier du Tacul supplies much more ice than the Glacier de Leschaux. However, if the Mer de Glace is considered in its broades ...

Ski Lift
A ski lift is a mechanism for transporting skiers up a hill. Ski lifts are typically a paid service at ski resorts. The first ski lift was built in 1908 by German Robert Winterhalder in Schollach/Eisenbach, Hochschwarzwald. Types * Aerial lifts transport skiers while suspended off the ground. Aerial lifts are often bicable ropeways, the "bi-" prefix meaning that the cables have two different functions (carrying and pulling). **Aerial tramways ** Chairlifts and detachable chairlifts ** Funifors ** Funitels ** Gondola lifts ** Hybrid lifts * Surface lifts, including T-bars, magic carpets, and rope tows. * Cable railways, including funiculars * Helicopters are used for heliskiing and snowcats for snowcat skiing. This is backcountry skiing or boarding accessed by a snowcat or helicopter instead of a lift, or by hiking. Cat skiing is less than half the cost of heliskiing, more expensive than a lift ticket but is easier than ski touring. Cat skiing is guided. Skiing at select, ...

Railway Companies Of France
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...

Metre Gauge Railways In France
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redef ...

Mountain Railways
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Tourist Attractions In Haute-Savoie
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 pa ...

List Of Highest Railways In Europe
This is a list of highest passenger railways in operation in Europe. It only includes non-cable railways whose culminating point is over 1,200 metres above sea level. Most of them are located in the Alps, where two railways, the Jungfrau and Gornergrat railways, exceed 3,000 metres and nine other exceed 2,000 metres, including four railway crossings. The Pyrenees, which come second in height, include several railways above 1,500 metres. In the Alps, the tree line and the permanent snow line lie respectively at about 2,000 and 3,000 metres.These lines are lower in Scandinavia and higher in southern Europe Because of the harsh weather conditions that prevail at those higher altitudes, maintaining working railways there is an expensive and difficult task. Snow, avalanches, rockslides and wind, added to the absence of protection by the forests, pose a challenge in every season. Lower elevation railways (even well below the tree line) are also exposed to more severe weather conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamonix - Accident Du 25 Août 1927 Au Viaduc Du Montenvers
Chamonix-Mont-Blanc ( frp, Chamôni), more commonly known as Chamonix, is a commune in the Haute-Savoie department in the Auvergne-Rhône-Alpes region of southeastern France. It was the site of the first Winter Olympics in 1924. In 2019, it had a population of 8,640. Situated to the north of Mont Blanc, between the peaks of the Aiguilles Rouges and the notable Aiguille du Midi, Chamonix is one of the oldest ski resorts in France. The Chamonix commune is popular with skiers and mountain enthusiasts. Via the cable car lift to the Aiguille du Midi it is possible to access the off-piste (backcountry) ski run of the ''Vallée Blanche''. Name The name Campum munitum, meaning fortified plain or field, had been used as early as 1091. By 1283 the name had been abbreviated to a similar form to the modern Chamonis. Other forms through the ages include Chamouny in 1581, Chamony in 1652, Chamouni in 1786, and the particular spelling Chamonix from 1793. Status Chamonix is the fourth-largest co ...

Aerial Lift
An aerial lift, also known as a cable car or ropeway, is a means of cable transport in which ''cabins'', ''cars'', ''gondolas'', or open chairs are hauled above the ground by means of one or more cables. Aerial lift systems are frequently employed in a mountainous territory where roads are relatively difficult to build and use, and have seen extensive use in mining. Aerial lift systems are relatively easy to move and have been used to cross rivers and ravines. In more recent times, the cost-effectiveness and flexibility of aerial lifts have seen an increase of gondola lift being integrated into urban public transport systems. Types Cable Car A cable car (British English) or an aerial tramway, aerial tram (American English), uses one or two stationary ropes for support while a separate moving rope provides propulsion. The grip of an aerial tramway is permanently fixed onto the propulsion rope. Aerial trams used for urban transport include the Roosevelt Island Tramway ( New Yor ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Overhead Lines
An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipment (OHE) * Overhead line equipment (OLE or OHLE) * Overhead lines (OHL) * Overhead wiring (OHW) * Traction wire * Trolley wire This article follows the International Union of Railways in using the generic term ''overhead line''. An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regular intervals. The feeder stations are usually fed from a high-voltage electrical grid. Overview Electric trains that collect their current from overhead lines use a device such as a pantograph, bow collector or trolley pole. It presses against the underside of the lowest overhead wire, the contact wire. Current collectors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
