Wenzhou Train Collision
The Wenzhou train collision was a railway accident that occurred on 23 July 2011, when a high-speed train travelling on the Yong-Tai-Wen railway line collided into the rear of another stationary train on a viaduct in Lucheng District, Wenzhou, Zhejiang province, China. The two trains derailed, and four carriages fell off the viaduct. 40 people were killed, and at least 192 were injured, 12 severely. This disaster was caused by both defects in railway signal design and poor management by the railway company. The collision is the only fatal crash involving high-speed rail (HSR) in China, and is the third-deadliest HSR accident in history, after the 1998 Eschede train disaster in Germany and 2013 Santiago de Compostela derailment in Spain. High speed was not a factor in the accident, however, since neither train was moving faster than , a moderate speed for a passenger train. Local officials responded to the accident by hastily conducting rescue operations and on-site buria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ou River (Zhejiang)
The Ou River () or Oujiang is the second-largest river in the Zhejiang province of eastern China. The river flows before finally reaching the city of Wenzhou and emptying into the East China Sea, into which it discharges of water annually. Shen Jiang (), Jiang Yongjia (), and Wenjiang () are all former names for this river. Fauna The Ou River has a rich fish fauna. A 2010 survey recorded 60 different fish species, with goldfish, bagrid catfish, and ''Pseudobagrus tenuis'' being the most prolific in range. Compared to a 1972 survey, 20 new species were recorded, including two alien species (Mozambique tilapia and largemouth bass); however, 34 species recorded in 1972 were absent in 2010, and overall fish density was lower. Goby ''Pseudorhinogobius aporus'' is endemic to the Ou River system: it is only known from a brook in the upper Ou River system. Notes References Rivers of Zhejiang {{China-river-stub ...

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] |
Balise Transmission Module
A balise ( ) is an electronic Radio Beacon, beacon or transponder placed between the Rail tracks, rails of a railway as part of an automatic train protection (ATP) system. The French language, French word ''wikt:balise, balise'' is used to distinguish these beacons from other kinds of beacons. Balises are used in the Contrôle de vitesse par balises, KVB signalling system installed on main lines of the French railway network, other than the high-speed TGV, Lignes à Grande Vitesse. Balises constitute an integral part of the European Train Control System, where they serve as "beacons" giving the exact location of a train. The ETCS signalling system is gradually being introduced on railways throughout the European Union. Balises are also used in the Chinese Train Control System versions CTCS-2 and CTCS-3 installed on high-speed rail lines in China, which is based on the European Train Control System. A balise which complies with the European Train Control System specification is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on a block of rail tracks to control railway signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent dispatchers and operators from causing accidents, both by informin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Train Control System
The European Train Control System (ETCS) is a train protection system designed to replace the many incompatible systems used by European railways, and railways outside of Europe. ETCS is the signalling and control component of the European Rail Traffic Management System (ERTMS). ETCS consists of 2 major parts: #trackside equipment #on-board (on train) equipment ETCS can allow all trackside information to be passed to the driver cab, removing the need for trackside signals. This is the foundation for future automatic train operation (ATO). Trackside equipment aims to exchange information with the vehicle for safely supervising train circulation. The information exchanged between track and trains can be either continuous or intermittent according to the ERTMS/ETCS level of application and to the nature of the information itself. The need for a system like ETCS stems from more and longer running trains resulting from economic integration of the European Union (EU) and the ...

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 ...

Railway Signalling
Railway signalling (), or railroad signaling (), is a system used to control the movement of railway traffic. Trains move on fixed rails, making them uniquely susceptible to collision. This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle. In the UK, the Regulation of Railways Act 1889 introduced a series of requirements on matters such as the implementation of interlocked block signalling and other safety measures as a direct result of the Armagh rail disaster in that year. Most forms of train control involve movement authority being passed from those responsible for each section of a rail network (e.g. a signalman or stationmaster) to the train crew. The set of rules and the physical equipment used to accomplish this determine what is known as the ''method of working'' (UK), ''method of operation'' (US) or ''safe-working'' (Aus.). Not all these methods require the use of p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
