Two persons were killed and six others injured when two coaches and engine of Guwahati-bound Capital Express from Bihar's Rajendra Nagar Terminal derailed in North Bengal on Tuesday night.

North East Frontier Railway officials said two unidentified male bodies were found from the coaches while six persons were injured in the derailment that occurred at around 9pm near Shamuktala Road station, about 32 km from Alipurduar Railway Division headquarters.

Initial reports had said that 10 persons were injured.

Rail traffic has been stopped in both up and down lines in a diverted route, the officials said.

Chief Public Relations Officer of NF Railway Pranav Jyoti Sharma said three helpline numbers -- 9002052957, 8585082833 and 03564-259935 -- have been issued for information on the derailment and rescue and relief operations.

It once again pushes for the case of use of LHB coaches in place of ICF.
Tragic.
Prayers with deceased and injured.

yeah very relevant indeed. You got my respect.

 

[anant_s]

unfortunately some see a funny side even in face of human tragedy.
i've been a great supporter and admirer of Chinese Railway technology, but loss of life irrespective of what caused it is a matter of sadness. Probably the only thing worse is mocking in such tragic times.
Hope someday we will rise above this hate.

what are these? and how will it prevent accidents?

@cirr what makes this news to appear on the PDF?

Yes, you have explained the advantages of the new trains.

I'd suggest the mod merge this thread into the following thread where rational discussion on technical issues is more likely.

lol...what else do you expect from this rather rotten individuals. Makes you wonder some people should have just swallowed instead of producing offspring.

Hello there.

During train crashes, the locomotive comes to a sudden stop but in absence of any braking effort, the coaches continue to move. now since they donot have a place to move on rails, the inertial mass has a tendency to climb over next stationary object. this is known as telescoping. What it means is that the rear coach will climb over its forward coach. This has been single largest cause of casualty during accidents as people get crushed under debris.

Now this phenomenon was studied and a a new design feature was developed by which coaches actually have a thinner section at the ends (the section near toilet or vestibule end). what it does, hat when there is sudden reduction in train speed due to accident, the thinner section gets crushed, while remaining bogie remains in horizontal configuration and doesnot climb over next one. This allows greater chance of survival as energy is absorbed and coach geometry is not disurbed (it can get de-railed but not climb of tipple). They also have a very tight coupling, that does not allow coaches to move free of each other for sometime after accident.
This is exactly what LHB coach does. ICF coaches donot have this property.

LHB Coach during accident

Dr. Anil kakodkar Committee formed on Railway safety measures, pointed out the same and asked IR to stop producing any more ICF coaches and introduce LHB coaches. It further recommended that ICF trains should not be more than 18 coaches long and should not run at more than 110 kph
Simulations done, indicated LHB caches are far safer than ICF counterparts

Response of ICF Coaches

Hence if LHB coaches are used, in statistically similar track conditions, casualty rates would come down.

I don't expect sympathies for it is a very high order human value, but a bit of decency at time of human tragedy isn't much to ask.

Today is a sad day for both nations. A plane crashed in Pakistan as well.

Sorry to hear that.
Global civil aviation sector too has been witnessing some tragic events in past few months (recent accident in Brazil).
Let us hope attention is drawn towards passenger safety and some immediate steps are taken.

Thanks mate, do we make LHB coaches in India? and why is there delay in using such coaches? How long before we completely convert all our trains into those coaches?

 

[anant_s]

do we make LHB coaches in India?

Yes we do at Rae bareli and Kapurthala

why is there delay in using such coaches?

Not delay exactly, these are progressively being inducted, but larger cost and only 2 factories (producing an annual combine of ~1500 LHB coaches), is leading to slower rate of replacement.

How long before we completely convert all our trains into those coaches?

Probably another decade
