Wenzhou Train Collision
The Wenzhou train collision occurred on 23 July 2011 when two high-speed trains travelling on the Yong-Tai-Wen railway line collided on a viaduct in Lucheng District, Wenzhou, Zhejiang province, People's Republic of China. The two trains Derailment, derailed, and four cars fell off the viaduct. 40 people were killed, at least 192 were injured, 12 of which were severe injuries. This disaster was caused by both critical defects in railway signal design and poor management by the railway company. Officials responded to the accident by hastily conducting rescue operations and ordering the burial of the derailed cars. These actions elicited strong criticism from Chinese media and online communities. In response, the government issued directives to restrict media coverage, which was met with limited compliance, even on state-owned networks. The collision is one of the only fatal crashes involving high-speed rail in China, high-speed rail (HSR) in China, and is the third-deadliest H ...

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 Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemi ...

People's Daily
The ''People's Daily'' () is the official newspaper of the Central Committee of the Chinese Communist Party (CCP). The newspaper provides direct information on the policies and viewpoints of the CCP. In addition to its main Chinese-language edition, the ''People's Daily'' is published in multiple languages. History The paper was established on 15 June 1948 and was published in Pingshan, Hebei, until its offices were moved to Beijing in March 1949. Ever since its founding, the ''People's Daily'' has been under direct control of the CCP's top leadership. Deng Tuo and Wu Lengxi served as editor-in-chief from 1948 to 1958 and 1958–1966, respectively, but the paper was in fact controlled by Mao Zedong's personal secretary Hu Qiaomu. During the Cultural Revolution, the ''People's Daily'' was one of the few sources of information from which either foreigners or Chinese could figure out what the Chinese government was doing or planning to do. During this period, an editorial in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fail-safe
In engineering, a fail-safe is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people. Unlike inherent safety to a particular hazard, a system being "fail-safe" does not mean that failure is impossible or improbable, but rather that the system's design prevents or mitigates unsafe consequences of the system's failure. That is, if and when a "fail-safe" system fails, it remains at least as safe as it was before the failure. Since many types of failure are possible, failure mode and effects analysis is used to examine failure situations and recommend safety design and procedures. Some systems can never be made fail-safe, as continuous availability is needed. Redundancy, fault tolerance, or contingency plans are used for these situations (e.g. multiple independently controlled and fuel-fed engines). Examples Mechanical or physical Examples inc ...

Balise Transmission Module
A balise is an electronic beacon or transponder placed between the rails of a railway as part of an automatic train protection (ATP) system. The French word ''balise'' is used to distinguish these beacons from other kinds of beacons. Balises are used in the KVB signalling system installed on main lines of the French railway network, other than the high-speed 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 called a Eurobalise. Overview A balise typically needs no power source. In response to radio ...

Track Circuit
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant 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 Train dispatcher, dispatchers and Manual block, operators from ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European Train Control System
The European Train Control System (ETCS) is the signalling and control component of the European Rail Traffic Management System (ERTMS). It is a replacement for legacy train protection systems and designed to replace the many incompatible safety systems currently used by European railways. The standard was also adopted outside Europe and is an option for worldwide application. In technical terms it is a type of positive train control (PTC). ETCS is implemented with standard trackside equipment and unified controlling equipment within the train cab. In its advanced form, all lineside information is passed to the driver wirelessly inside the cab, removing the need for lineside signals watched by the driver. This will give the foundation for a later to be defined automatic train operation. 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 int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Train Control System
The Chinese Train Control System (CTCS, ''simpl.chinese:'' 中国列车控制系统) 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 based on 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 consists of 5 different levels (Level 0 to Level 5). 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 sig ...
