Flop isliye hai cuz log prefer ni karte isko..warna passengers ki kami ni hai..Plus Lucknow now has a very good airline connection to Delhi to log ab Airline prefer karte hai especially after COVID and expressways bhi hai u can reach Delhi in 6 hours now by road easily..
Plus nobody wants to wake up at 4 in the morning isko pakadne liye and uske bad CC mein bthke 8 hours travel kre congested..
LKO already has Shatabdi and Rajdhani connection daily..
