Chinese Train Control System
The Chinese Train Control System (CTCS, ) is a train control system used on railway lines in People's Republic of China. CTCS is similar to the European Train Control System (ETCS). It has two subsystems: ground subsystem and onboard subsystem. The ground subsystem may include balise, track circuit, radio communication network (GSM-R), and Radio Block Center (RBC). The onboard subsystem includes onboard computer and communication module. CTCS Levels There are 5 different levels (Level 0 to Level 4). Levels 2, 3, and 4 are back-compatible with lower levels. CTCS Level 0 (CTCS-0) For railway lines where operational speeds are below : * Track configuration: Track circuit * Cab configuration: CTCS Universal Cab Signalling (UCS) + Train operating service unit (TOSU/LKJ) + Driver Machine Interface (DMI). Level 0 is used on lines with conventional trackside signalling. Train drivers follow trackside signals primarily, with cab signals as back-up. UCS receives train fixed block occ ...

Rail Transport In The People's Republic Of China
Rail transport is an important mode of long-distance transportation in China. As of 2024, the country had more than of railways, the 2nd longest network in the world. By the end of 2023, China had more than of high-speed rail (HSR), the longest HSR network in the world. The railway sector in China is essentially operated by the central government. Almost all rail operations are handled by the China State Railway Group Company, Limited, a state-owned company created in March 2013 (as China Railway Corporation) after the dissolution of the Ministry of Railways. It was converted into a joint-stock company and placed under the control of the Ministry of Finance in June 2019. China's railways are the busiest in the world. In 2019, railways in China delivered 3.660 billion passenger trips, generating 1,470.66 billion passenger-kilometres and carried 4.389 billion tonnes of freight, generating 3,018 billion cargo tonne-kilometres. Freight traffic turnove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Railway Signalling In China
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th ...

Chinese Railway Signalling
Railway signals in China are based on OSShD signals used by 25 countries of the former USSR, eastern Europe and adjacent countries. There are four observer countries. Overview Railway signals in China: Semaphore Semaphore signals based somewhat on British practice. Use Red and White home signals, and Yellow and Black distant signals. Apart from Red=Halt and single G=Clear, the lights of a semaphore signal at night do not match their colour light equivalents. There also more colour light aspects than semaphore aspects. Colourlight Colour lights: single green means full speed on straight, red means stop, with remainder meaning something in between. In China, double green is a more restrictive aspect than single green. If one of the green lamps fails, a less restrictive aspect is displayed which is potentially dangerous. Because of that lamp proving is necessary. Standards exported China is building or has built new standard gauge railways in Africa, and these are bei ...

LTE-M
LTE-M or LTE-MTC ("Long-Term Evolution Machine Type Communication") is a type of low-power wide-area network radio communication technology standard developed by 3GPP for machine-to-machine and Internet of Things (IoT) applications. LTE-M includes eMTC ("enhanced Machine Type Communication"), also known as LTE Cat-M1, whose specification was frozen in June 2016 as part of 3GPP Release 13 ( LTE Advanced Pro), as well as LTE Cat-M2. Competing 3GPP IoT technologies include NB-IoT and EC-GSM-IoT. The advantage of LTE-M over NB-IoT is its comparatively higher data rate, mobility, and voice over the network, but it requires more bandwidth, is more costly, and cannot be put into guard band portion of the frequency band for now. Compared to LTE Release 12 Cat-0 modem, an LTE-M model is claimed to be 80% less expensive (in terms of the bill of materials), support up to 18 dB better coverage, and a battery lifetime that can last up to several years. In March 2019, the Global Mobile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moving Block
In railway signalling, a moving block is a signalling block system where the blocks are defined in real time by computers as safe zones around each train. This requires both knowledge of the exact location and speed of all trains at any given time, and continual communication between the central signalling system and the train's cab signalling system. Moving block allows trains to run closer together (reduced headway) while maintaining required safety margins, thereby increasing the line's overall capacity. It may be contrasted with fixed block signalling systems. Communications Based Train Control (CBTC) and Transmission Based Signalling (TBS) are two signalling standards that can detect the exact location of trains and transmit back the permitted operating speed to enable this flexibility. The European Train Control System ( ETCS) also has the technical specifications to allow moving block operations, though no system uses it currently, besides test tracks. Information about ...

Global Positioning System
The Global Positioning System (GPS) is a satellite-based hyperbolic navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephone or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls, and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. Overview The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was launched in 1978 an ...

High-speed Rail In China
The high-speed rail (HSR, ) network in the People's Republic of China (PRC) is the List of high-speed railway lines, world's longest and most extensively used. The HSR network encompasses newly built rail lines with a design speed of . China's HSR accounts for two-thirds of the world's total high-speed railway networks. Almost all HSR trains, track and service are owned and operated by the China Railway Corporation under the brand China Railway High-speed (CRH). High-speed rail developed rapidly in China since the mid-2000s. CRH was Campaign to raise the speed of railway travel in China, introduced in April 2007 and the Beijing–Tianjin intercity railway, Beijing-Tianjin intercity rail, which opened in August 2008, was the first passenger dedicated HSR line. Currently, the HSR extends to all Provinces of China, provincial-level administrative divisions and Hong Kong SAR with the exception of Macau SAR. Notable HSR lines in China include the Beijing–Kunming high-speed train, B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Odometer
An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two (electromechanical). The noun derives from ancient Greek , ''hodómetron'', from , ''hodós'' ("path" or "gateway") and , ''métron'' ("measure"). Early forms of the odometer existed in the ancient Greco-Roman world as well as in ancient China. In countries using Imperial units or US customary units it is sometimes called a mileometer or milometer, the former name especially being prevalent in the United Kingdom and among members of the Commonwealth of Nations, Commonwealth. History Classical Era Possibly the first evidence for the use of an odometer can be found in the works of the ancient Roman Pliny the Elder, Pliny (NH 6. 61-62) and the ancient Greek Strabo (11.8.9). Both authors list the distances of routes traveled by Alexander the Great (r. 336-323 BC) as by his bematists Diog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Of Railway Signals
The application of railway signals on a rail layout is determined by various factors, principally the location of points of potential conflict, as well as the speed and frequency of trains and the movements they require to make. Non-provision of signals Before discussing the application of signals, it is useful to highlight some situations where signals are ''not'' required: * Sidings generally need not be signalled, as all movements within them are made cautiously at low speed. * Tram lines frequently employ "running on sight" without any signals (similar to road traffic) except at junctions. * Where movement authorities are passed to drivers exclusively by means other than fixed signals (e.g. by written or verbal authority), token, or cab signalling. Purpose of signals Signals exist primarily to pass instructions and information to drivers of passing trains. The driver interprets the signal's indication and acts accordingly. The most important indication is 'danger', w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Train Protection
Automatic train protection (ATP) is the generic term for train protection systems that continually check that the speed of a train is compatible with the permitted speed allowed by signalling, including automatic stop at certain signal aspects. If it is not, ATP activates an emergency brake to stop the train.
