Most probably it is just to transfer the rake. This rake reaches MFR at 4:45 so that it could depart as MFR NIR Pass at 5:10. Upon reaching NIR, the same rake departs from NIR at 6:20 as NIR JBP Pass.
Wonder why can't they simply make this MFR JBP Pass!
The rake which departs from JBP in the evening, reaches NIR at 23:00, and later departs as this Ghost Pass at 3:45.
