Azerbaijan State Railway
Azerbaijan Railways ( az, Azərbaycan Dəmir Yolları) is the national state-owned rail transport operator in the Republic of Azerbaijan. The , gauge network is electrified at 3 kV (3,000 V) DC. The headquarters of the Azerbaijan Railways is in the capital Baku. Azerbaijan Railways is a successor of Soviet Railways, which itself was the successor of Russian Imperial Railways. Following the collapse of the Soviet Union in 1991 its railway system broke up into national railway systems of various former Soviet republics from which the independent Republic of Azerbaijan and the Azerbaijan Railways both emerged in that year. The first railway line in Azerbaijan was laid in 1878 and was opened in 1880 in the suburbs outside Baku. There are of rail tracks out of which 72% or are single track and 28% or are double tracks. Of the total exploitation length of route 43% or are electrified. About 38% of the length of the railway routes or are equipped with full ...

Closed Joint-stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. ...

State-owned
State ownership, also called government ownership and public ownership, is the ownership of an industry, asset, or enterprise by the state or a public body representing a community, as opposed to an individual or private party. Public ownership specifically refers to industries selling goods and services to consumers and differs from public goods and government services financed out of a government's general budget. Public ownership can take place at the national, regional, local, or municipal levels of government; or can refer to non-governmental public ownership vested in autonomous public enterprises. Public ownership is one of the three major forms of property ownership, differentiated from private, collective/cooperative, and common ownership. In market-based economies, state-owned assets are often managed and operated as joint-stock corporations with a government owning all or a controlling stake of the company's shares. This form is often referred to as a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shirvan (city)
Shirvan (from fa, شروان, translit=Shirvān; az, Şirvan; Tat: ''Şirvan''), also spelled as Sharvān, Shirwan, Shervan, Sherwan, Šervān, and Chirvan. is a historical Iranian region in the eastern Caucasus, known by this name in both pre-Islamic Sasanian and Islamic times. Today, the region is an industrially and agriculturally developed part of the Azerbaijan Republic that stretches between the western shores of the Caspian Sea and the Kura River, centered on the Shirvan Plain. History Etymology Vladimir Minorsky believes that names such as Sharvān (Shirwān), Lāyzān and Baylaqān are Iranian names from the Iranian languages of the coast of the Caspian Sea. There are several explanations about this name: * Shirvan or Sharvan are changed forms of the word "Shahrbān" ( fa, شهربان, links=no) which means "the governor". The word "Shahrban" has been used since Achaemenian Dynasty as "Xshathrapawn" (satrap) to refer to different states of the kingdom. * Sher ...

Centralized Traffic Control
Centralized traffic control (CTC) is a form of railway signalling that originated in North America. CTC consolidates train routing decisions that were previously carried out by local signal operators or the train crews themselves. The system consists of a centralized train dispatcher's office that controls railroad interlockings and traffic flows in portions of the rail system designated as CTC territory. One hallmark of CTC is a control panel with a graphical depiction of the railroad. On this panel, the dispatcher can keep track of trains' locations across the territory that the dispatcher controls. Larger railroads may have multiple dispatcher's offices and even multiple dispatchers for each operating division. These offices are usually located near the busiest yards or stations, and their operational qualities can be compared to air traffic towers. Background Key to the concept of CTC is the notion of ''traffic control'' as it applies to railroads. Trains moving in opposit ...

Automatic Block Signaling
Automatic block signaling (ABS), spelled automatic block signalling or called track circuit block (TCB ) in the UK, is a railroad communications system that consists of a series of signals that divide a railway line into a series of sections, called ''blocks''. The system controls the movement of trains between the blocks using automatic signals. ABS operation is designed to allow trains operating in the same direction to follow each other in a safe manner without risk of rear-end collision. The introduction of ABS reduced railways' costs and increased their capacity. Older manual block systems required human operators. The automatic operation comes from the system's ability to detect whether blocks are occupied or otherwise obstructed, and to convey that information to approaching trains. The system operates without any outside intervention, unlike more modern traffic control systems that require external control to establish a flow of traffic. History The earliest way of ...

Double Track
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 a ...

Single Track (rail)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contac ...

Rail Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A ''loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
