The fact that i am still traveling in the train must hold some credibility for what i am going to suggest next. I'd you travel by higher classes, then this is not a train tug day you should be traveling in. Reasons you ask are enumerated below:
1. It is averagely an hour late from its start.
(This is primarily because it arrived late)
2....

Stopped well short of ghaziabad, for god knows what for an hour.
3. Bodies are generally untidy like they have been used for decades without cleaning.(2 AC was worst hit as there was no water till mighal sarai)
4. The AC is switched off as soon as the train stops.
5. The train failed to reach any of the stops in time. (Generally 4-5 hours late)
So if you value your time, please don't make a mistake of booking your travel in this train. The number of available tickets even on the last day may tempt you, but try to understand the fact why are there so many seats available in the first place.
@railway dept- please change the timings of the train in case you are u unable to make good it's ETA & ETDs.
