El Ferdan Railway Bridge
The El Ferdan Railway Bridge is a swing bridge that spans the western shipping lane of the Suez Canal near Ismailia, Egypt. It is the longest swing bridge in the world, with a span of . The bridge is no longer functional due to the New Suez Canal, expansion of the Suez Canal completed in 2015 which added a parallel shipping lane just east of the existing bridge, cutting off the Sinai Railway, railway into Sinai. As of 2021 a second swing bridge spanning the new eastern shipping lane is under construction. When completed, service on the bridge can resume. History The first El Ferdan Railway Bridge over the Suez Canal was completed in April 1918 for the Palestine Railways#Sinai Military Railway, Sinai Military Railway.Hughes, 1981, page 17 It was considered a hindrance to shipping so after the World War I, First World War it was removed. A steel swing bridge was built in 1942 (during the World War II, Second World War), but this was damaged by a steamship and removed in 1947. A doub ...

Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, or ...

Suez Crisis
The Suez Crisis, or the Second Arab–Israeli war, also called the Tripartite Aggression ( ar, العدوان الثلاثي, Al-ʿUdwān aṯ-Ṯulāṯiyy) in the Arab world and the Sinai War in Israel,Also known as the Suez War or 1956 War; other names include the ''Sinai war'', ''Suez–Sinai war'', ''1956 Arab–Israeli war'', the Second Arab–Israeli war, ''Suez Campaign'', ''Sinai Campaign'', ''Kadesh Operation'' and ''Operation Musketeer'' was an invasion of Egypt in late 1956 by Israel, followed by the United Kingdom and France. The aims were to regain control of the Suez Canal for the Western powers and to remove Egyptian president Gamal Abdel Nasser, who had just swiftly nationalised the foreign-owned Suez Canal Company, which administered the canal. Israel's primary objective was to re-open the blocked Straits of Tiran. After the fighting had started, political pressure from the United States, the Soviet Union and the United Nations led to a withdrawal by the ...

Railway Bridges In Egypt
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 facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-track Railway
A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track. Advantages and disadvantages Single track is significantly cheaper to build and maintain, but has operational and safety disadvantages. For example, a single-track line that takes 15 minutes to travel through would have capacity for only two trains per hour in each direction safely. By contrast, a double track with signal boxes four minutes apart can allow up to 15 trains per hour in each direction safely, provided all the trains travel at the same speed. This hindrance on the capacity of a single track may be partly overcome by making the track one-way on alternate days, if the single track is not used for public passenger transit. Long freight trains are a problem if the passing s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-track Railway
A double-track railway usually involves running one track in each direction, compared to a single-track railway where trains in both directions share the same track. Overview In the earliest days of railways in the United Kingdom, most lines were built as double-track because of the difficulty of co-ordinating operations before the invention of the telegraph. The lines also tended to be busy enough to be beyond the capacity of a single track. In the early days the Board of Trade did not consider any single-track railway line to be complete. In the earliest days of railways in the United States most lines were built as single-track for reasons of cost, and very inefficient timetable working systems were used to prevent head-on collisions on single lines. This improved with the development of the telegraph and the train order system. Operation Handedness In any given country, rail traffic generally runs to one side of a double-track line, not always the same side as ...

El Qantara, Egypt
El Qantara ( ar, القنطرة, al qantara, the bridge) is a northeastern Egyptian city on both sides of the Suez Canal, in the Egyptian governorate of Ismailia, northeast of Cairo and south of Port Said. The two parts of the city are connected by a high-level fixed road bridge, the Mubarak Peace Bridge. The bridge makes a connection between the division of Africa, and Asia, making El Qantara a Border town. History El Qantara was built next to a site of an ancient city Sele (, , ''Tcharou''). During World War I, Kantara, as it was referred to by the Allied troops, was the site of Headquarters No. 3 Section, Canal Defences and Headquarters Eastern Force during the latter stages of the Defence of the Suez Canal Campaign and the Sinai Campaign of 1916. The massive distribution warehouse and hospital centre supported and supplied all British, Australian and New Zealand operations in the Sinai from 1916 until final demobilization in 1919. Beginning in January 1916, a ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Suez Canal Bridge
The Suez Canal Bridge, also known as the Egyptian–Japanese Friendship Bridge, Al Salam Bridge, Al Salam Peace Bridge or Mubarak Peace Bridge, is a road bridge crossing the Suez Canal at El-Qantara, whose name means "the bridge" in Egyptian Arabic. The bridge links the continents of Africa and Asia. Design and construction The bridge was built with assistance from the Japanese government. The main contractor was Kajima Corporation. The Japanese grant, accounting for 60% of the construction cost (or 13.5 billion yen), was agreed to during the visit of then-President Hosni Mubarak to Japan in March 1995, as part of a larger project to develop the Sinai Peninsula. Egypt bore the remaining 40% (9 billion yen). The bridge was opened in October 2001. The bridge, which has a clearance over the canal and is long, consists of a cable-stayed main span and two long approach spans. The height of the two main pylons supporting the main span is each. The towers were designed in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suez Canal Overhead Powerline Crossing
The Suez Canal overhead powerline crossing is a major electrical power line built across the Suez Canal in 1998, located near Suez, Egypt. It is designed for two 500 kV circuits. Because the required clearance over the Suez Canal is , the overhead line has two high pylons (one on either side of the crossing) in spite of its small span width of . The pylons each have four crossarms: three for the conductors and one for catching the conductors in case of an insulator string failure. Significant developments in the region The crossing was part of a major drive to develop the areas surrounding the Suez Canal, including other projects such as the Ahmed Hamdi Tunnel under the Suez Canal (completed in 1981), the El Ferdan Railway Bridge, and the Suez Canal Bridge (completed in 2001). It was constructed by a consortium between STFA Enerkom and Siemens. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ahmed Hamdi Tunnel
The Ahmed Hamdi Tunnel is a 1640 metre long car tunnel under the Suez Canal, at Shallufa. The tunnel is named after Ahmed Hamdi, an Egyptian engineer and general killed in action during the October War. It has two lanes of traffic, one in each direction, and connects the Asian Sinai Peninsula to the town of Suez on the African mainland.
