I once went via Gomti from Lucknow to Delhi in 1A [the only time I splurged on First AC] and was allotted the prime berth - lower in a coupe. Co-incidentally, the singular HA1 coach is the only one in the entire train that is not encroached upon[even CC has overstuffed passengers], if you discount the guy who boarded 1A from Kanpur outers to Kanpur Central couple of kms away :p.
That one had excellent railfanning opportunity because for this train, intervening station travelers make it so tough that even in AC...
more... Chair Car, one can't leave their seat.
I would have taken a VB back from Delhi to Lucknow but it the AYC VB goes off very early and that too, from ANVT making it tough to catch.
