After observing these replies from some IRI Members I have concluded that KOAA is an apt station over crowded ones like HWH or SDAH. Even the SLN Route is considered rather than the congested CNB Route. So I have framed the following stations route for such a train :-
.
Kolkata Chitpur - Asansol - Dhanbad - Gaya - Mughalsarai - Varanasi - Sultanpur - Lucknow - Bareilly - Moradabad - Hapur - Ghaziabad - Old Delhi - Ambala Cantt - Ludhiana - Jalandhar City - Beas - Amritsar.

PS: 16 Stations en route with Brand New ICF All AC Rake (Pantry Incl). Loco can be a HWH WAP-7 between KOAA & MB followed by IZN WDM as Hapur Route is under Electrification :-)
