I suggest a weekly/ twice a week MAQ-NZM SF in following TT / route:
MAQ Dep 1500, MAO 1940 (follow VSG-PATNA schedule upto ET) ET 1900. From ET to NZM, this can run in between TN and Karnatka exp. Slots are available. Arrival at NZM 0800.
Return trip: NZM 1930 and run in between GT and TN slot upto ET. ET arr 0745. Follow PATNA-VSG slot upto PNVL arr 2150 and then follow DR-TEN TT to arrive at MAQ 1200.
Will...
more... give a proper train from MAQ-SWV stretch to Delhi as well as reduce the load on 12617/12618.
Can be called as Mangala Exp, as the our grand old Mangala Exp s now Mangala Lakshadweep Exp. Depending on response/ slots, TT and frequency can be adjusted.
