Thanks for posting the detailed message. As per the official timings, the train has "already left Mathura at 10:15AM". Not only that, this official status was updated at 11:12AM, which is about 1 hour after the train's supposed departure from Mathura.
We do several validations, before showing the info on the map. If we find that the status of the train was very recently updated, that too 1 hour after departure, and it says that the train "has already left Mathura without delay", then we go ahead and use that information.
In this...
more... case, from what you say, the official info is very wrong, since the train is "just approaching Nzm".
We are helpless in this situation, because a recently updated official timestamp says the train has already crossed Mathura.
As for warning in big letters, we already have put the same in BIG, RED BOLD letters, that because of the fog situation, the official timings can be WRONG. Once again, sorry, we are helpless about that.
You can also see in the "Rail News" section where the official enquiry, 139 etc. are not able to give correct info, and bloggers like yourself are the source of 100% correct info.
Thanks for the posting your comment. Many of our other passengers will benefit from your train updates.
Please drop in quick status notes against the particular train 2904 as it crosses various stations, and this will greatly benefit our community. Thanks.
