Road–rail Vehicle
A road–rail vehicle or a rail–road vehicle is a dual-mode vehicle which can operate both on rail tracks and roads. They are also known as two-way vehicles (german: Zweiwegefahrzeug), hi-rail (from ''highway'' and ''railway'', or variations such as high-rail, HiRail, Hy-rail), and rail and road vehicles. They are often converted road vehicles, keeping their normal wheels with rubber tires, but fitted with additional flanged steel wheels for running on rails. Propulsion is typically through the conventional tires, the flanged wheels being free-rolling, used to keep the vehicle on the rails; the rail wheels are raised and lowered as needed. There are also purpose-built road–rail vehicles. In case of jeep trains, road wheels are directly replaced with railway wheels. Vehicles with tires need special areas like level crossings to change modes. A vehicle on caterpillar tracks rather than road wheels, which allows mode change anywhere without the need to use a level crossing ...

Level Crossing
A level crossing is an intersection where a railway line crosses a road, Trail, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an Overpass#Railway, overpass or tunnel. The term also applies when a light rail line with separate Right-of-way (railroad), right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the location, but often early level crossings had a Flagman (rail), flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broad Gauge
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the used by standard-gauge railways. Broad gauge of , commonly known as Russian gauge, is the dominant track gauge in former Soviet Union (CIS states, Baltic states, Georgia and Ukraine), Mongolia and Finland. Broad gauge of , commonly known as Irish Gauge, is the dominant track gauge in Ireland, and the Australian states of Victoria and Adelaide. Broad gauge of , commonly known as Iberian gauge, is the dominant track gauge in Spain and Portugal. Broad gauge of , commonly known as Indian gauge, is the dominant track gauge in India, Pakistan, Bangladesh, Sri Lanka, Argentina, Chile, and on BART (Bay Area Rapid Transit) in the San Francisco Bay Area. This is the widest gauge in common use anywhere in the world. It is possible for trains on both Iberian gauge and Indian gauge to travel on each other's tracks with no modifications in the vast majority of cases. History In Gr ...

Standard Gauge
A standard-gauge railway is a railway with a track gauge of . The standard gauge is also called Stephenson gauge (after George Stephenson), International gauge, UIC gauge, uniform gauge, normal gauge and European gauge in Europe, and SGR in East Africa. It is the most widely used track gauge around the world, with approximately 55% of the lines in the world using it. All high-speed rail lines use standard gauge except those in Russia, Finland, and Uzbekistan. The distance between the inside edges of the rails is defined to be 1435 mm except in the United States and on some heritage British lines, where it is defined in U.S. customary/Imperial units as exactly "four feet eight and one half inches" which is equivalent to 1435.1mm. History As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narrow Gauge
A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard . Most narrow-gauge railways are between and . Since narrow-gauge railways are usually built with tighter curves, smaller structure gauges, and lighter rails, they can be less costly to build, equip, and operate than standard- or broad-gauge railways (particularly in mountainous or difficult terrain). Lower-cost narrow-gauge railways are often used in mountainous terrain, where engineering savings can be substantial. Lower-cost narrow-gauge railways are often built to serve industries as well as sparsely populated communities where the traffic potential would not justify the cost of a standard- or broad-gauge line. Narrow-gauge railways have specialised use in mines and other environments where a small structure gauge necessitates a small loading gauge. In some countries, narrow gauge is the standard; Japan, Indonesia, Taiwan, New Zealand, South Africa, and the Aust ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tankette
A tankette is a tracked armoured fighting vehicle that resembles a small tank, roughly the size of a car. It is mainly intended for light infantry support and scouting.T-27 Tankette (from the 'battlefield.ru' website, with further references cited. Accessed 2008-02-21.) Colloquially it may also simply mean a small tank. Several countries built tankettes between the 1920s and 1940s, and some saw limited combat in the early phases of . The vulnerability of their light armour, however, eventually led armies to abandon the concept with some exceptions such as the more modern German Wiesel (Weasel) series. ...

Type 95 So-Ki
The Type 95 So-Ki was an armored railroad car of the Imperial Japanese Army. It was used for patrolling and guarding railway lines in both Manchuria and Burma. The chassis was based on the Type 95 Ha-Go light tank. The Type 95 So-Ki had light armor and no fixed weapons armament. Hand-held weapons by the crew would be the only armament available. It had a simple suspension system with bogie wheels suspended on bell cranks on each side of the chassis. The tracks were driven through the front sprockets. There were three small return wheels. The Type 95 So-Ki was unique as it had both a track and wheel drive system. The vehicle could be changed between railway line wheels mode and track mode for ground use within a few minutes time as it had retractable wheels. In addition, the width of the wheels could be adjusted to the various widths of the rail gauge In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a ...

Japanese Empire
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationalism and t ...

FAI Armoured Car
The FAI ''(Ford-A Izhorskiy)'' armoured car was a replacement for the D-8 armoured car, used by the Soviet Union from the early 1930s to early 1940s. Description The FAI was built on the chassis of the GAZ-A car, a licensed copy of the American Ford A. This chassis was the major weakness of the FAI. Most commercial car chassis were not powerful enough to move a useful amount of armour or firepower on the battlefield. The Germans were known to get round this particular problem by designing a car chassis that was intended from the outset for both civilian and military vehicles and which was used successfully in at least one German armoured car family of this period. However, armoured cars based on commercial car chassis were, for the most part, road-bound, thinly armoured and lightly armed. The FAI was a typical example of this class of vehicle with a single 7.62 mm DT machine-gun in a revolving turret. The armour was sufficient to stop most shell fragments and small arms f ...

BAD-2
BAD-2 was a Soviet experimental amphibious armored car, that could be also converted to run on railroad tracks (see ''draisine''). The changing for rail mode took 30 minutes. Only one prototype was built in 1932, designed by engineer P. N. Syachentov. Dimensions The BAD-2 armored vehicle, weighs 4.6 tons, and is about 5.5 meters long, about 2 meters wide, and about 2.2 meters high. Conversion The BAD-2 had a set of special rail road wheels used on the railway. It takes about half an hour to replace all the wheels. After completion, the BAD-2 can be used as a light rail armored vehicle. Rubber tracks can also be installed on the rear wheels of the armored vehicle to transform into a half-track A half-track is a civilian or military vehicle with regular wheels at the front for steering and continuous tracks at the back to propel the vehicle and carry most of the load. The purpose of this combination is to produce a vehicle with the cro ... vehicle to enhance its off-road ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
