Rail service and travel by rail in India and Bangladesh

Without wishing to detract from the argument about the better build of these cars, no doubt having already saved countless lives, a caveat is that the amount of damage inflicted is dependent on the speed at the moment of impact. In physics, the kinetic energy scales with the square of the speed, meaning a train going at double the speed has four times the kinetic energy, or a 41% greater speed means a 100% increase in kinetic energy. It is this kinetic energy that is chiefly responsible for things being torn apart on impact. So one should be careful comparing damage without also knowing the speeds involved in both cases.

We know the speed (50mph) and we also know that an ICF consist would have had several cars split open at that speed.

Gosh, I too am impressed that the LHB carriages did not telescope or rip apart, as well as the front of the loco looking "fairly okay"... I wonder what type of goods wagons were run into, maybe quite low level, given the loco's frontal condition.
I seem to remember reading that couplings should not break apart in an accident, but I can't be sure? Definitely a blessing that it was not ICF old style stock!
The video lingers on the points at one time, and it certainly looks like many bolts are missing...

The last car of the freight train, a Guard Van was completely demolished and apparently dissipated a significant amount of energy. The next wagon was damaged beyond repair.

For comparison of damage BTW, in the rear end collision of a freight into Kanchanjungha Express in North Bengal with an ICF consist, the last car was flattened and destroyed beyond recognition. The third and fourth car from the rear lost structural integrity and the second car from the rear climbed on top of the freight locomotive. The speed at impact was 40kph, half the speed of this one, but the momentum/KE of the loaded freight train arguably was more than that of a loaded 24 car passenger, though it was a relatively light train as far as freights go.

The LHB cars did exceptionally well in the Coromandal Exp. crash at Bahanaga Bazar too in the 130kph crash though the first car lost structural integrity. The fact that 5 of the cars in the front were General Unreserved Second Class played a key role in the significant level of casualty.

Here are some interior photos of the first delivered Vande Bharat Sleeper EMU...

AC 2 Tier Sleeper:

AC First Class Compartment:

All berths are 6' long.

They are capable of being certified for 200kph (125mph), but are currently certified for 160kph (100mph) where civil speed limits allow.

According to an article i9n the website greaterkashmir.com (which unfortunately has a bunch of malicious links in it) the first through service from New Delhi to Srinagar is slated to start operating over the completed Kashmir Rail Link in January 2025.

The holdup , as discussed earlier in this thread, has been the so called Tunnel T1/T33 which crosses the Main Thrust Fault, a 70 M stretch of very weak and crumbled rock formation with huge amount of water incursion. The tunnel through that section has now been completed and stabilized, and track laying work is in progress, to be completed by 20th December.

Although there is yet to be a firm date announcement, the scuttlebutt is that service will be inaugurated around 26th of January, India's Republic Day. In addition to local intra-state service between Jammu and Baramulla, there will at least be one through service from New Delhi to Srinagar, operated by a Sleeper Vande Bharat consist. It will be an overnight train departing New Delhi around 7pm, arriving in Srinagar the next day at around 8am.

Here is a fair use excerpt from the article posted in the malicious link infested web site:

Banihal, Nov 17: In a move aimed at improving connectivity with Kashmir, the New Delhi-Srinagar Vande Bharat Express is set to start in January 2025.

The train will cover a distance of 800 km in less than 13 hours.

The semi-high speed train will depart from New Delhi at 7 pm and reach Srinagar at 8 am the next day. A trial train is currently being run between Sangaldan and Reasi.

. . . .

Engineers say that work is currently underway on Tunnel T33 and will be completed in about a month.

Officials said, “The work will be completed on all 4 stations between Reasi and Katra by December 20, after which the Director Safety will observe a trial train run for 15 days till January 5.”

According to officials, after January 5, the remaining work on this track would be completed. Officials of Northern Railway said that Prime Minister Narendra Modi would probably dedicate the New Delhi-Baramulla railway line to the nation on January 26.
