A new LHB rake is need for LTT-ALD Duronto Express.
Then it's old icf can be used for LTT-LKO AC Express hence making it biweekly too
The rake of 22109 can have an RSA with LTT-Karmali Premium.
People are paying much more for trains like Duronto and Premium than for non-sf AC Express (LTT-LKO).
Its...
more... just because of the rake sharing with LTT-ALD Duronto that LTT-Karmali Premium has odd timetable.
22110 should depart from NZM on Thursday instead of Wednesday, as the 16:00 Rajdhani slot is vacant on thursday and reach LTT on Friday. This will help in improvement of schedule of 22110 too.
Then the rake can depart as LTT-Karmali AC Premium on the timeslot for LTT-ERS Duronto Express on Friday.
Also the train should run upto Mao and then can be parked back at Karmali the whole day as there is space problem at Mao. Or if Vasco-da-gama has space then the premium can run upto Vasco itself. In reverse Direction, Evening departure from Vasco/Mao should be there, reaching Mumbai on sunday morning.
Also, a LHB rake for Pune-NZM Duronto is needed.
