double decker will be flop but jaipur lucknow intercity type train can be super hit....600odd km with speed 65 can be covered easily in 9-10 hours... cc can be 4 general coach, 6 seating coach, 2 sleeper coach, 2 ac chair car , 1 third ac and 2 slr... there are volvos and normal buses running between these 2 cities also express trains carries lot of load and many ticket remain waitlisted...
1 rake can run triweekly...and later made daily if patroage is good..
