Ltt-Lucknow Sup is really a super alternate to Pushpak but still people prefer Pushpak in the first place,
Pushpak is owned/managed by NER and halts are seriously more, Halts like Khandwa, Habibganj, Lalitpur, Orai and Unnao can be done away with but then i dont think the last three halts can be withdrawn...
LTT-LKO and Udyognagri of CR are really good alternates...
