Indeed.
Ek eisa hi kissa he Mahananda express ka (many years back).
I was to travel from APDJ to DLI on 21 Jun and there was no seat in any train except Mahananda.
So, I made 2 tickets of 19 Jun and 20 Jun of Mahananda express thinking that I'll be able to take any one of them atleast on 21.
And...
more... you know what, on 21, 2 Mahanands departed APDJ of dates 18 and 19 Jun with 1 hour of difference.
I cancelled both the tickets with full refund and got AC2 ticket of 18-Jun Mahananda from TTE inside the train.
Even the TTE was laughing on my condition.
But all in all, if I consider my original travel plan of 21-Jun then I actually departed APDJ ~4 hours early and reached DLI ~12 hours delayed.
Such was the horror of Mahananda then, don't know what is the situation now.
