A Rail Network Can Never Be Completely SafeHuman Errors and The 'Irony of Automation'The Role of External FactorsIncreased Collaboration Key For Upcoming LinesAs Seetha Ram and his research associate Nikhil Bugalia explain, the first assumption should always be that a rail system can never be safe enough. Both of them recently contributed to the redaction of a paper called 'Handbook on high speed rail and quality of life'. "A railway organisation's pursuit of safety should never stop," the handbook reads. "For complex socio technical systems such as railways, safety should be achieved thro…See more on railway technologyEstimated Reading Time: 9 minsPeople also askWhat are the advantages and disadvantages of high speed rail?What are the advantages and disadvantages of high speed rail?High speed rail (HSR) is a new type of passenger rail transport tha t is faster and more comfortable than the normal traffic train.

IntroductionTopics Covered by The Working GroupConclusionsSince the introduction of Gas Insulated Substations (GIS) in the late 1960s, sulphur hexafluoride (SF6) has become the favourite insulating and arc quenching medium thanks to its remarkable characteristics. However, SF6 has the major drawback of presenting a global warming potential (GWP) if released to the atmosphere, which is 23,500 times higher than CO2 and a lifetime in the atmosphere of around 3200 years according to IPCC Assessment Report 5 (AR5) from 2014. Due to these properties, it is one of th…See more on electra.cigre.orgGas insulated switchgear up to 550 kV, 63 kA, 5000 A Type 8DQ1 assets.siemens energy/siemens/assets/api/uuid:e22e1805 0b...PDF fileSince 1974 we have supplied gas insulated substations for voltage levels of up to 420 kV.
