Booking status vs running status.
High demand from enroute stations in Odisha as there are only 2 weekly trains to Mumbai and LTT-VSKP has RL quota. So who'll book ticket with this high waiting in SL and 3A ? One side the train runs empty and on another side ticket needing people are choosing alternatives. As VSKP has also a daily train to LTT. This weekly express should run both up and down having GNWL quota for ECoR stations.
