Vivek Express: ऊंचे नीचे रास्ते और मंज़िल तेरी दूर.

I am not saying that you are wrong, sir. You are perfectly correct in saying that we should check if the update is coherent and some basic common sense should be used when doing the updates. In my opinion, that should be the case only for information that is not explicitly stated by the official sources.
But I believe there should be no room for any outside input, or any individual creativity in updating schedules sir. It is IR that runs the train and decides it's schedules and operating procedures. You may 'painstakingly assimilate the TT', but we are not the ones running the train. There should be absolutely no room for error in the train's...

schedule.
And just to nitpick in this case, trains getting cancelled after bookings opening is not unprecedented and for all we know, it could be an error on IRCTC's part that the bookings are still open and an official notification may have followed to the same effect. This does sound like a stretch, but again, the main point is that, we are not the ones running the train and we should, in no way, let any guesswork get into the way for the schedules.
Things like loco links, platform numbers, coach composition etc are not listed on the official website and these are also somewhat trivial things that would not affect a passenger much even if they are reported incorrectly on the website. But a schedule is something very fundamental, and there should be no room for error.
