Indeed so! After the Howrah Duronto was diverted via the main line, the need for a more realistic alternative to the Howrah Duronto is definitely required! With all due respect, paying extra money, and going via the main line can never be justificable for a SL Passenger from Howrah side!
But Sanket raises a good point too, an bi-weekly AC express without any dyanamic fare can do wonders on this route!
Why not start by regularising this train?
