Coromandel Express derails

Instead of flagging vandhe bharat which are not much diff than current coaches  better invest on safety . Life matters most  not the looks or speed

Very tragic accident.

For the time being we don't need vande Bharat and bullet train but need to upgrade our system

Everything is important.

Does anyone one know why did the derailment happen in the first place? Despite of a green signal, was there a blockage on tracks , ? What happened to driver , guard and tte. Were they injured. Did driver jump just before the derailment.? Driver must have time to save his life as the derailment happens as he can see 

Mobile tech 5G but indian rail technology at 1G level

Someone paste Modi Ji photo inspecting the accident..  He has reached there everything will be under control 

no point in counting death when govt just give 10 lakh ex gratia.

Quick question. Are people, who travelled without a ticket, eligible for a compensation?

I see every train is crowded let it go any where.

Unless government takes action to control population the situation will go beyond control.

Photographer, body identification, is sharing his experience.

Photos of unidentified bodies have been released 

we need to unite in the times of adversity and stand up for the cause of facing the national calamity collectively and bring about effort to amend whatever is wrong , together we will rise again , we have withstand problem but we shall overcome obstruction and achieve pice and solidarity in the times of calamity and  disaster...

Which boggies most affected in this accident.? i e - AC Tier1-2-3, sleeper, General ?

Can we expect new episodes of ahat and fear files now ?

Looks like everything is in hand of GODS now , humans are worthless . 

In February, three months before the deadly train accident in Odisha that claimed 288 lives, a top Railways official had flagged "serious flaws in the signalling system". The officer also warned that if the signal maintenance system was not monitored, it could lead to “serious accidents”.

is it allowed to enter in to loop line at full speed? i read that max is 50km-65km. how it entered at full speed? 

So sad and upsetting what happened. I wish the Govt took some long-term care of uprooted families e.g. gave them jobs besides compensation.

This is an informative article about the core issue of the accident: electronic interlocking relay failure: https://www.moneycontrol.com/news/india/odisha-... CBI probe will reveal if it was due to human negligence/error or 1-in-a-million technical fault (no machines/electronics are 100% failsafe, but 99.99%)

I am not any railway engineer but I think that there is scope for improvement in upgrading the track infrastructure instead of all the focus all the time on new trains only like Vande Bharat. The upgrade from ICF coaches to LHB on huge number of trains was a very good move as LHB coaches are safer. But they should make continuous similar safety improvements to track infrastructure.

Ideally, when 1 safety mechanism fails there should be be several others in place to save lives. It must not be a system with a single point of failure like this electronic interlocking malfunctioning to divert the train to the loop line, and signal remaining green which tells the driver to go at full permitted speed.

Loop lines can be constructed much longer so trains coming on same track have some time to apply emergency brakes. and parked trains can be farther from relay switches. I read that loop lines are generally 750 metres in length to accommodate full-length goods train with multiple engines. Indian Railways, however, has been encouraging the construction of loop lines of around 1500 meters. They should make this top priority then and upgrade loop lines all over India.

Also, if anti-collision systems like Kavach is installed on loop lines too plus their length longer, then a train despite accidentally entering on same track as another train can still be stopped safely - i.e. with one fail-safe mechanism such as this allegedly robust electronic interlocking failing in extremely rarest of rare case, there is another safety system in place.

I feel that railways focus is too much on showing off posh looking upgraded trains. That is all good but should come after upgrades to track infrastructure.

In today's paper, says priliminary investigation indicates deliberate interference in signal.

I don't think it is deliberate or some terror/sabotage plan - it is unlikely that anyone would deliberately interfere with signaling or electronic interlocking - firstly it requires expertise of the track control system to manipulate it and secondly requires access to it which only railway employees have. That's not how terrorists work. Unko agar train ka accident karana hai woh bomb phodenge.

This is either a human oversight or shortcuts taken in safety protocols while operating the track control system, in which case the concerned person should be punished severely. Or it could also be a bug in the embedded system software or hardware component that they use. Electronic machines are reliable 99.9% of the time, but in extremely rare cases, they can fail.

Electronic interlocking is microprocessor-based with built-in safety features like automatic blocking of signals, track circuits, points. It is also used in many other countries - USA, Europe, Australia, Japan, Germany, France, China, South Korea etc. The system Indian Railways uses is compliant with some of the highest safety standards and certifications such as SIL4.

Another possibility as one Railway Board member said is it could be a physical error, whereby someone has done some digging without seeing the cables. Hopefully CBI will find out. They should work on putting multiple safety systems in place and eliminating a single point of failure.

Here are the most recent findings about this disaster:

Odisha Rly Staff May Have 'Manually' Changed Track System to 'Save Time'? New Theory in Coromandel Train Crash: https://www.news18.com/india/coromandel-express-accident-reason-odisha-technician-manually-changed-interlocking-system-8009251.html As the CBI begins probe into the Odisha train accident, another angle related to the cause of the incident has come to light. It is being said that the signalling technician, instead of using system laid down by the Railways, manually completed the interlocking work of the tracks, bypassing certain nodes in a manner that the safety system would not recognise anything was amiss.

This would have gone undetected but for one thing. The point, 17A, the report quoted a senior official who is in the know of things. This manual act did not relay to the system that while the “all clear” signal was achieved, the point remained directed towards the loop line. The report further quoted officials as saying that those in the Railways dealing with this said signal maintainers and others at the station are well authorised by codes and manuals to officially disconnect an interlocking system for any reason, if they think safety is at risk.

The report mentioned that a location box, typically placed along tracks, holds a junction of connections to the point motor (the movable piece of rail that physically guides a train to its designated track when there are two divergent tracks), the signalling lights, the track-occupancy detectors, and virtually every critical piece that makes the interlocking work seamlessly. Interlocking is a crucial safety mechanism and ensures trains move without any conflict with each other, preventing accidents. The main line on which the Coromandel Express was to pass, could not have got a green signal — a line clear signal — if the boom barrier of the level crossing was not down.

By looping the location box, the technician achieved an “all clear” signal for the Coromandel Express, overriding the fail-safe logic manually. This would have gone undetected but for one thing. The point, 17A, the report quoted a senior official who is in the know of things. This manual act did not relay to the system that while the “all clear” signal was achieved, the point remained directed towards the loop line.

The report further quoted officials as saying that those in the Railways dealing with this said signal maintainers and others at the station are well authorised by codes and manuals to officially disconnect an interlocking system for any reason, if they think safety is at risk. The officials said that this helped them bypass a cumbersome “due process" of disconnecting an interlocking system that is also time consuming — pointing to a possible explanation why technicians on the ground “tampered" with the location box.

If this is indeed true, the guilty must be charged with homicide.

Another extremely sad finding:

At least 40 bodies retrieved from the derailed bogies of the Coromandel Express rake involved in the three-train crash in Odisha’s Balasore may have been electrocuted by snapped overhead cables as they didn’t have any external injury: https://timesofindia.indiatimes.com/city/bhubaneswar/at-least-40-on-coromandel-express-may-have-died-due-to-electrocution/articleshow/100776997.cms Live overhead cables fell on the compartments. Many passengers succumbed to injuries caused due to the collision but others due to electrocution (after) coming in contact with overhead LT (low tension) line. The cables apparently snapped after the Yeshwantpur (Bengaluru)-Howrah Express crashed into the derailed bogies of the Coromandel Express.

Thousands of aeroplanes fly daily, why would somebody ram it in WTC ?

Good news or a band news can't tell

Any interlock functions like....... if  and only if certain condition is mate then only another works. Normally limit switches which senses motion or position of a lever (instrumentation device) is used for such purposes.

From the news it appears, interlocking for changing of tracks and signals failed. Imo, both can happen.. malfunction or tampering, bypass of such device.

CAG as well as railways own employee had raised questions about gov spending (or rather lack of and the need) on railway safety equipments. So whom to blame directly or indirectly is anyone's guess.
