African Integrated High Speed Railway Network
The African Union of Railways is an organisation under the auspices of the new African Union dealing with railways. It is similar to the International Union of Railways (UIC). Overview Africa's railways are disjointed and disconnected. The AUR hopes to rectify things. By 2012 a number of railway projects had been proposed to rectify this, some of which would make connections between international railway systems. This interconnectivity would require the development of more standardised systems. Standards Gauge The AUR sees that conversion to a common gauge is too difficult and expensive due to the gauge muddle, but based on reports from the World Bank, does see the following gauges as preferred in the following regions: * North - * South - mostly connected and quite strong. * East - (but Tanzania, Kenya, Uganda and isolated Ethiopia are ). * West - (but Sierra Leone and Nigeria are isolated). * Other ** South Africa NG ** Eritrea NG ** Algeria NG ...

Organisation
An organization or organisation (Commonwealth English; see spelling differences), is an entity—such as a company, an institution, or an association—comprising one or more people and having a particular purpose. The word is derived from the Greek word ''organon'', which means tool or instrument, musical instrument, and organ. Types There are a variety of legal types of organizations, including corporations, governments, non-governmental organizations, political organizations, international organizations, armed forces, charities, not-for-profit corporations, partnerships, cooperatives, and educational institutions, etc. A hybrid organization is a body that operates in both the public sector and the private sector simultaneously, fulfilling public duties and developing commercial market activities. A voluntary association is an organization consisting of volunteers. Such organizations may be able to operate without legal formalities, depending on jurisdiction, includ ...

Railroad Tie
A railroad tie, crosstie (American English), railway tie (Canadian English) or railway sleeper (Australian and British English) is a rectangular support for the rails in railroad tracks. Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Railroad ties are traditionally made of wood, but prestressed concrete is now also widely used, especially in Europe and Asia. Steel ties are common on secondary lines in the UK; plastic composite ties are also employed, although far less than wood or concrete. As of January 2008, the approximate market share in North America for traditional and wood ties was 91.5%, the remainder being concrete, steel, azobé (red ironwood) and plastic composite. Tie spacing may depend on the type of tie, traffic loads and other requirements, for example 2640 concrete ties per mile on North American mainline railroads to 2112 timber ties per mile ...

Railway Stations In Eritrea
This article is a list of the railway stations in Eritrea. The Eritrean Railway originally ran from Massawa, a port on the Red Sea, via the capital Asmara to Agordat. The line can be divided into three sections (Massawa-Asmara; Asmara-Keren; Keren-Agordat). Additionally there was until WW2 a potash line, that was used also for civilian service. Massawa to Asmara The route was built between 1887 and 1910 by the Italians, who made the two main stations (Asmara and Massawa) with typical structures of railway stations in small Italian cities. As of 2008, this is the only section open. Asmara to Keren This section (with the stations) was built between 1911 and 1923. The railway generally followed the Anseba River and one of its tributaries through the mountains between Zazzega and Halib Mentel. Keren to Agordat This section was built between 1924 and 1929. Beyond Agordat Beyond Agordat, the rails were laid as far as Bishia, another , with plans to extend to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Stations In Ethiopia
Current railway stations in Ethiopia are served by standard gauge railways of the National Railway Network of Ethiopia which is mostly under construction, except the Addis Ababa–Djibouti Railway. Other stations were built for the in 2018 still operating metre gauge Ethio-Djibouti Railways, although this railway has officially been superseded by the new ''Addis Ababa-Djibouti Railway''. The following list contains dedicated railway stations with at least a single platform for passengers to enter or to leave trains. Train stops on open stretches without platform can outnumber train stops in railway stations by a 2:1 margin, but the former are not included in the lists. The railways usually also have a number of freight yards and dry ports for freight handling, but these are not counted as well. Standard gauge railways Description of railway stations Railway stations mostly have a single platform for passengers to enter or to leave trains. These platforms allow access witho ...

Africa Four Rail Triple Gauge
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dual Gauge
In railway engineering, "gauge" is the transverse distance between the inner surfaces of the heads of two rails, which for the vast majority of railway lines is the number of rails in place. However, it is sometimes necessary for track to carry railway vehicles with wheels matched to two different gauges. Such track is described as dual gauge – achieved either by addition of a third rail, if it will fit, or by two additional rails. Dual-gauge tracks are more expensive to configure with signals and sidings, and to maintain, than two separate single-gauge tracks. It is therefore usual to build dual-gauge or other multi-gauge tracks only when necessitated by lack of space or when tracks of two different gauges meet in marshalling yards or passenger stations. Dual-gauge tracks are by far the most common configuration, but triple-gauge tracks have been built in some situations. Background The rail gauge is the most fundamental specification of a railway. Rail tracks and whee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piggy-back (transportation)
Piggyback transportation refers to the transportation of goods where one transportation unit is carried on the back of something else. It is a specialised form of intermodal transportation and combined transport. Etymology ''Piggyback'' is a corruption of ''pickaback'', which is likely to be a folk etymology alteration of ''pick pack'' (1560s), which perhaps is from ''pick'', a dialectal variant of the verb ''pitch''. Examples Rail In rail transport, the practice of carrying trailers or semi-trailers in a train atop a flatcar is referred to as "piggybacking". Early drawings of the Liverpool & Manchester Railway c1830 show road coaches being piggybacked on railway flat wagons. The rail service provided for trucks which are carried on trains for part of their journey is referred to as a rolling road, or rolling highway. A related transportation method is the rail transport of semi-trailers, without road tractors, sometimes referred to as "trailer on flatcar (TOFC)". In ...

Bogie Exchange
Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge. To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks (the chassis containing the wheels and axles of the car), and installing a new bogie with differently spaced wheels. It is generally limited to wagons and carriages, though the bogies on diesel locomotives can be exchanged if enough time is available. Wagons and carriages Bogie wagons can have their gauge changed by lifting them off one set of bogies and putting them back down again on another set of bogies. The pin that centres the bogies and the hoses and fittings for the brakes must be compatible. A generous supply of bogies of each gauge is needed to accommodate the ebb and flow of traffic. The bogies and wagons also need to have standardized hooks, etc., where they may be efficiently lifted. The two wheel sets on four-wheel wagons can be change ...

Variable Gauge Axles
A variable gauge system allows railway vehicles in a train to travel across a break of gauge between two railway networks with different track gauges. For through operation, a train must be equipped with special bogies holding variable gauge wheelsets containing a variable gauge axle (VGA). The gauge is altered by driving the train through a gauge changer or gauge changing facility. In effect, the track widens or narrows. As the train passes through the gauge changer, the wheels are unlocked, are moved closer together, or further apart, and are then re-locked. Installed variable gauge systems exist within the internal network of Spain, and are installed on international links between Spain/France (Spanish train), Sweden/Finland (Swedish train), Poland/Lithuania (Polish train) and Poland/Ukraine (Polish train). A system for changing gauge without the need to stop is in widespread use for passenger traffic in Spain, for services run on a mix of dedicated high-speed lines (using St ...

Containerisation
Containerization is a system of intermodal freight transport using intermodal containers (also called shipping containers and ISO containers). Containerization is also referred as "Container Stuffing" or "Container Loading", which is the process of unitization of cargoes in exports. Containerization is the predominant form of unitization of export cargoes, as opposed to other systems such as the barge system or palletization. The containers have standardized dimensions. They can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another—container ships, rail transport flatcars, and semi-trailer trucks—without being opened. The handling system is completely mechanized so that all handling is done with cranes and special forklift trucks. All containers are numbered and tracked using computerized systems. Containerization originated several centuries ago but was not well developed or widely applied unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Port
A dry port (sometimes referred to as an inland port) is an inland intermodal terminal directly connected by road or rail to a seaport, operating as a centre for the transshipment of sea cargo to inland destinations. In addition to their role in cargo transshipment, dry ports may also include facilities for storage and consolidation of goods, maintenance for road or rail cargo carriers and customs clearance services. The location of these facilities at a dry port relieves competition for storage and customs space at the seaport itself. A dry inland port can speed up the flow of cargo between ships and major land transportation networks, creating a more central distribution point. Inland ports can improve the movement of imports and exports, moving the time-consuming sorting and processing of containers inland, away from congested seaports. Background The term inland port is used in a narrow sense in the field of transportation systems to mean a specialized facility for intermod ...
