This is a day train to SC, and to reach SC by 11am, it must depart KRMR around 3 to 3:30am, I am damn sure if it departs at that time, it will be 79.85% empty from KRMR till NZB.
IMO, depart KRMR at 5am, depart nzb by 9am, arrive sc at 1pm. In the return direction change the train timings, depart this train from SC after Ajanta, because there's 2 and half hours gap between Ajanta and Nagarsol exp. 100% it'll be packed from SC till KRMR. Preferred departure timing from SC, exactly at 7pm, arrive nzb at 10:40, depart nzb by 11pm arrive krmr at 3am.
Hence...
more... 6 hours primary maintenance at SC, 2 hours secondary maintenance at KRMR. This timing will also unburden grandmother Ajanta..
