IR really needs to work over the TT of NZM JBP trains. Shridham and Mahakaushal run with a difference of about 10min between Delhi and JHS both ways. Similarly, MPSK trails NZM SF (now Gondwana) by 10min all the way from NZM to JBP. Further, even Durgawati runs sandwiched between Shridham and Mahakaushal in the NZM JHS stretch.
