Transmission Balise-locomotive
Transmission balise-locomotive (Dutch: Transmissie Baken Locomotief) (TBL) (English: "Beacon-to-Locomotive Transmission") is a train protection system used in Belgium and (until 2021) on Hong Kong's East Rail line. Versions TBL1 The TBL system is designed to stop a train passing a red signal, with operating speeds of up to 160 km/h. In 2006 13% of the Belgium train network used the original TBL system, introduced in 1982. The system requires the train driver to manually acknowledge a warning when passing a double yellow signal (similar to the Memor/ Le Crocodile system), as well as stopping a train automatically if it passes a red signal. TBL1+ TBL1+ began to be installed on the Belgian rail network in 2006, with full conversion to the system expected by 2012. The system is a development of TBL1, but uses Eurobalises, providing compatibility for later reconfiguration to an ETCS system. An additional safety measure is the addition of an additional balise 300m up-line, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Train Protection System
A train protection system is a railway technical installation to ensure safe operation in the event of human error. Development Train stops The earliest systems were train stops, as still used by the New York City Subway, the Toronto subway, the London Underground, the Moscow Subway (only on the older lines) and the Berlin S-Bahn. Beside every signal is a moveable arm. If the signal is red, levers connected to valves on any passing train hit the arm, opening the brake line, applying the emergency brake, If the signal shows green, the arm is turned away from the levers and there is no contact. The Great Western Railway in the UK introduced its ' automatic train control' system in the early years of the 20th century. Each distant signal had before it a ramp between the running rails. If the signal showed green, the ramp was energised with a low voltage current which was passed to the locomotive when a shoe came into contact with the ramp. A bell rang in the locomotive's ca ...

Great Western Main Line
The Great Western Main Line (GWML) is a main line railway in England that runs westwards from London Paddington to . It connects to other main lines such as those from Reading to Penzance and Swindon to Swansea. Opened in 1841, it was the original route of the first Great Western Railway which was merged into the Western Region of British Railways in 1948. It is now a part of the national rail system managed by Network Rail with the majority of passenger services provided by the current Great Western Railway franchise. The line has recently been electrified along most of its length. The eastern section from Paddington to was electrified in 1998. Work to electrify the remainder of the route started in 2011 with an initial aim to complete the work all the way to Bristol by 2016, but in that year the section through Bath to Bristol Temple Meads was deferred with no date set for completion because costs had tripled.

MTR Hyundai Rotem EMU
The Hyundai Rotem EMU (also known as R-Train or 1141B) () is a current model of heavy rail electric multiple units used on the Mass Transit Railway in Hong Kong. The 9-car sets are manufactured by Hyundai Rotem for the North South Corridor, an extension of the East Rail line, at a cost of HK$4 billion. 37 trainsets were ordered in December 2012 and the first delivery took place in 2015, while a further 6 trains were ordered in May 2020. Originally scheduled to enter service in late-2017 to early-2018, the trains gradually entered service from 6 February 2021. All train sets were put into service in 2022, replacing the Metro Cammell EMUs and displacing the SP1900 EMUs to the Tuen Ma Line. Formation The formation ranges from D001/D003 (Trainset 1) to D127/D129 (Trainset 43). Like the previous SP1900s and Metro Cammell EMUs, one car is still reserved for the first class in each train set. The 9-car formation is shorter than the previous 12-car East Rail Line trains, due to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sha Tin To Central Link
The Sha Tin to Central Link (abbreviated SCL; ) is an extension of the MTR rapid transit network. It is divided into two sections. The first section, named "Tuen Ma line (Phase 1)”, runs from Tai Wai station in the New Territories to Hung Hom station in Kowloon. The Tai Wai–Hung Hom segment connected the Ma On Shan line and West Rail line, forming the new Tuen Ma line. Operation of the Tai Wai to Kai Tak section began on 14 February 2020. The opening of the section from Kai Tak to Hung Hom was delayed and opened on 27 June 2021. In anticipation of the Tuen Ma line, the existing Kwun Tong line was extended from its previous terminus at Yau Ma Tei to Whampoa station. This extension includes the new Ho Man Tin station to provide interchange with the Tuen Ma line. The Kwun Tong line extension was opened on 23 October 2016.

West Rail Line
The West Rail line () was a rapid transit line that formed part of the Mass Transit Railway (MTR) system in Hong Kong until 27 June 2021. Coloured magenta on the MTR map, the line ran from Tuen Mun to Hung Hom, with a total length of , in 37 minutes. The railway connected the urban area of Kowloon and the new towns of Yuen Long, Tin Shui Wai and Tuen Mun in the northwestern New Territories. The line was the second of three lines built and operated by the Kowloon-Canton Railway Corporation (KCRC), then known as the KCR West Rail (). It was designed to suburban rail standards similar to that of KCR's first line, now the East Rail line, anticipating freight and intercity services to Mainland China, although the latter role was ultimately superseded by the Guangzhou–Shenzhen–Hong Kong Express Rail Link Hong Kong section as part of the China Railway High-speed network. After KCRC's merger of operations with the MTR Corporation on 2 December 2007, the West Rail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communications-based Train Control
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This makes railway traffic management safer and more efficient. Metros (and other railway systems) are able to reduce headways while maintaining or even improving safety. A CBTC system is a "continuous, automatic train control system utilizing high-resolution train location determination, independent from track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and trainborne and wayside processors capable of implementing automatic train protection (ATP) functions, as well as optional automatic train operation (ATO) and automatic train supervision (ATS) functions," as defined in the IEEE 1474 standard.1474.1–1999 – IEEE Standard for Communications-Ba ...

Safety-critical
A safety-critical system (SCS) or life-critical system is a system whose failure or malfunction may result in one (or more) of the following outcomes: * death or serious injury to people * loss or severe damage to equipment/property * environmental harm A safety-related system (or sometimes safety-involved system) comprises everything (hardware, software, and human aspects) needed to perform one or more safety functions, in which failure would cause a significant increase in the safety risk for the people or environment involved. Safety-related systems are those that do not have full responsibility for controlling hazards such as loss of life, severe injury or severe environmental damage. The malfunction of a safety-involved system would only be that hazardous in conjunction with the failure of other systems or human error. Some safety organizations provide guidance on safety-related systems, for example the Health and Safety Executive (HSE) in the United Kingdom. Risks of thi ...

Automatic Warning System
The Automatic Warning System (AWS) was introduced in the 1950s in the United Kingdom to provide a train driver with an audible warning and visual reminder that they were approaching a distant signal at caution. Its operation was later extended to give warnings for; * A colour light signal displaying a double yellow (steady or flashing), single yellow or red aspect * A reduction in permissible speed * A temporary or emergency speed restriction * An automatic barrier crossing locally monitored (ABCL), an automatic open crossing locally monitored (AOCL), or an open crossing (OC). AWS was based on a 1930 system developed by Alfred Ernest Hudd and marketed as the "Strowger-Hudd" system. An earlier contact system, installed on the Great Western Railway since 1906 and known as automatic train control (ATC), was gradually supplanted by AWS within the Western Region of British Railways. Principles of operation Information is conveyed by magnetic fields to the moving train thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
