Dhaka–Chittagong High-speed Railway
The Dhaka–Chittagong high-speed railway is a proposed high-speed rail line connecting Dhaka, the capital and largest city, with the southeast harbour city of Chittagong. The project is estimated to cost ৳96,752 crore (US$11.4 billion). The travel time between Dhaka and Chittagong will be 73 minutes for trains stopping at intermediate stations, and 55 minutes for nonstop trains. The ticket cost for one-way journey will be ৳2,000 without any discount or concession, more than three times higher than a conventional seat on current inter-city trains. History On May 31, 2018, Bangladesh Railway signed an agreement with the China Railway Design Corporation and Mazumder Enterprise. This contract is designed to verify the design and feasibility of proposed high-speed train lines. According to this agreement, feasibility and design work will be completed in December 2019 at a cost of Tk102.10 crore. The government of Bangladesh is bearing this cost. It is expected to reduce tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
25 KV AC Railway Electrification
Railway electrification systems using alternating current (AC) at are used worldwide, especially for high-speed rail. It is usually supplied at the standard utility frequency (typically 50 or 60Hz), which simplifies traction substations. The development of 25kV AC electrification is closely connected with that of successfully using utility frequency. This electrification is ideal for railways that cover long distances or carry heavy traffic. After some experimentation before World War II in Hungary and in the Black Forest in Germany, it came into widespread use in the 1950s. One of the reasons why it was not introduced earlier was the lack of suitable small and lightweight control and rectification equipment before the development of solid-state rectifiers and related technology. Another reason was the increased clearance distances required where it ran under bridges and in tunnels, which would have required major civil engineering in order to provide the increased clearance t ...

Overhead Catenary
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] |
High-speed Rail
High-speed rail (HSR) is a type of rail system that runs significantly faster than traditional rail, using an integrated system of specialised rolling stock and dedicated tracks. While there is no single standard that applies worldwide, lines built to handle speeds above or upgraded lines in excess of are widely considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains mostly operate on standard gauge tracks of continuously welded rail on grade-separated rights of way with large radii. However, certain regions with wider legacy railways, including Russia and Uzbekistan, have sought to develop a high speed railway network in Russian gauge. There are no narrow gauge high-speed trains; the fastest is the Cape gauge Spirit of Queensland at . Many countries have developed, or are currently building, high-speed rail infrastructure to connect major citie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Intermediate Station
A train station, railway station, railroad station or depot is a railway facility where trains stop to load or unload passengers, freight or both. It generally consists of at least one platform, one track and a station building providing such ancillary services as ticket sales, waiting rooms and baggage/freight service. If a station is on a single-track line, it often has a passing loop to facilitate traffic movements. Places at which passengers only occasionally board or leave a train, sometimes consisting of a short platform and a waiting shed but sometimes indicated by no more than a sign, are variously referred to as "stops", "flag stops", " halts", or "provisional stopping places". The stations themselves may be at ground level, underground or elevated. Connections may be available to intersecting rail lines or other transport modes such as buses, trams or other rapid transit systems. Terminology In British English, traditional terminology favours ''railway station' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metre-gauge Railway
Metre-gauge railways are narrow-gauge railways with track gauge of or 1 metre. The metre gauge is used in around of tracks around the world. It was used by European colonial powers, such as the French, British and German Empires. In Europe, large metre-gauge networks remain in use in Switzerland, Spain and many European towns with urban trams, but most metre-gauge local railways in France, Germany and Belgium closed down in the mid-20th century, although many still remain. With the revival of urban rail transport, metre-gauge light metros were established in some cities, and in other cities, metre gauge was replaced by standard gauge. The slightly-wider gauge is used in Sofia. Examples of metre-gauge See also * Italian metre gauge * Narrow-gauge railways A narrow-gauge railway (narrow-gauge railroad in the US) is a railway with a track gauge narrower than standard .

Railway Lines In Bangladesh
The following is a list of conventional lines of rail transport in Bangladesh. History The first railway line in Bangladesh was laid in 1862 by the British Raj. At that time Bangladesh didn't exist and its land was part of the Bengal Presidency. On 15 November of that year, Eastern Bengal Railway, the predecessor of Bangladesh Railway, opened the first railway line from Darshana railway station to Jagati railway station. In 1885 another railway line was built from Narayanganj to Mymensingh. In 1895, the railway line from Comilla to Chittagong was built. In 1914, a new railway was built from Akhaura to Tongi. After three years of construction, the railway line that connects Shayestaganj to Habiganj was opened in 1915. Another section from Shayestaganj to Balla was opened in 1929. Before the partition of India, many railway lines were built in Eastern Bengal, such as Chittagong–Dohazari, regional lines in Mymensingh region and others. After 1947, East Bengal got 2606.59 km ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
