African Union Of Railways
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 ** Alg ...

Organisation
An organization or organisation ( Commonwealth English; see spelling differences) is an entity—such as a company, or corporation or an institution ( formal organization), or an association—comprising one or more people and having a particular purpose. Organizations may also operate secretly or illegally in the case of secret societies, criminal organizations, and resistance movements. And in some cases may have obstacles from other organizations (e.g.: MLK's organization). What makes an organization recognized by the government is either filling out incorporation or recognition in the form of either societal pressure (e.g.: Advocacy group), causing concerns (e.g.: Resistance movement) or being considered the spokesperson of a group of people subject to negotiation (e.g.: the Polisario Front being recognized as the sole representative of the Sahrawi people and forming a partially recognized state.) Compare the concept of social groups, which may include non-or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dual Gauge
Dual gauge railroad track has three or four rails, allowing vehicles of two track gauges to run on it. Signalling and sidings are more expensive to install on dual gauge tracks than on two single gauge tracks. Dual gauge is used when there is not enough room for two single tracks or when tracks of two different gauges meet in marshalling yards or train stations. Background The rail gauge is the most fundamental specification of a railway. Rail tracks and Wheelset (rail transport), wheelsets are built within engineering tolerances that allow optimum lateral movement of the wheelsets between the rails. Pairs of rails that become too wide or narrow in gauge will cause derailments, especially if in excess of normal gauge-widening on curves. Given the requirement for gauge to be within very tight limits, when the designed distance between the pair of wheels on a wheelset differs even slightly from that of others on a railway, track must be built to two specific gauges. That is ... [...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 Rail transport in Ethiopia, 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.

Africa Four Rail Triple Gauge
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, corruption, colonialism, the Cold War, and neocolonialism. Despite this low concentration of wealth, recent economic expansion and a large and young populatio ... [...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 Human locomotion A person carrying someone else on their back is most commonly seen in the modern day in the form of a parent carrying an underage child, either for travelling or for children's games. It can involve the carrier crawling on hands and knees with the child straddling over the back like riding a horse, or with the carrier standing upright with the child hugging or cradled behind the back, often with the child's arms leaning over the carrier's shoulders and legs wrapping around the flanks. Piggybacking may also feature in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie Exchange
A bogie ( ) (or truck in North American English) comprises two or more wheelsets (two wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly in a road train or in railway bogie exchange). It may include suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Variable Gauge Axles
Variable gauge systems allow railway vehicles to travel between two railways with different track gauges. Vehicles are equipped with variable gauge axles (VGA). The gauge is altered by driving the train through a gauge changer installed at the break of gauge which moves the wheels to the gauge desired. 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 Standard gauge) and older lines (using Iberian gauge). Similar systems for freight traffic are still in their infancy, as the higher axle weight increases the technological challenge. Although several alternatives exist, including transferring freight, replacing individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Containerisation
Containerization is a system of intermodal freight transport using intermodal containers (also called shipping containers, or ISO containers). Containerization, also referred as container stuffing or container loading, is the process of unitization of cargoes in exports. Containerization is the predominant form of unitization of export cargoes today, 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 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 until after World Wa ... [...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 intermo ...

Intermodal Container
An intermodal container, often called a shipping container, or a freight container, (or simply "container") is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different Mode of transport, modes of transport – such as from container ship, ships to Rail transport, trains to Semi-trailer truck, trucks – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerization, containerized intermodal freight transport system, but smaller numbers are in regional use as well. It is like a boxcar that does not have wheels. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. These containers are known by many names: cargo container, sea container, ocean container, container van or sea van, sea can or C can, or MILVAN, or SEAVA ...
