Didn't see the video, because I've read about the CRS report. And a few things are concerning.

Enough walkie-talkies weren't available with the division. Isn't that the most basic tool of communication between the people responsible for operations.

the automatic signal wasn't working since 5:30 in the morning, why no steps were taken to rectify it. Or why the section was converted temporarily to absolute block.

Even if TA/912 was issued, how 5 trains were allowed in the block section at the same time. And even in that the MPS wasn't mentioned.

Were the staff untrained about protocols, because except Kanchenjunga no train followed the prescribed speed limit or waiting for a few minutes on every signal. Shouldn't a loco pilot know these things which even a lot of railfans know.

Why the goods loco pilot was overspeeding, was he under some time bound orders from above, because it was a clear day and a slow train could've been stopped in time after spotting another train standing ahead.

The same thing happened with the Gonda derailment, everyone knew that the tracks were unfit, but no steps were taken, even caution order wasn't issued. Now everyone is busy shifting blame on each other.

Till when everyone from the top brass to the grassroot workers will show incompetence. And till when people's life will be treated cheaper than a PR stunt. Someone needs to take responsibility and take it as soon as they can.

The video details exactly the same.
Systemic failures at multiple levels caused the accident.

Looks like not following speed restriction in TA912 was pretty common there as neither the document given mentioned speed restriction to follow neither were the LPs properly trained in that matter so whoever knew it followed and others just bypassed.

Relying on mobile networks for communication in such critical work environments is a horrible idea. The zone involved should be severely punished for not providing walkie talkie to the LPs and guard.

Multiple accounts of automatic signalling failures being reported and no proper action taken to find out why it's failing so often and fixing it.

Kavach system should be implemented across Railway network on priority basis.

People travel with peace of mind and safety thinking that Indian Railways is a robust organisation with utmost priority to safety operated by professionals but these things coming out of the report are pretty frightening. Feels like many things are like "jaise chalta hai vaise chalne de" in Indian Railways.
If such things continue people will loose faith in Railways and look for alternative options.
