I feel that the Shtbs' having short distance travel, like the NDLS CDG (244kms), NDLS Kalka (269kms), NDLS Kathgodam (282kms) should be retained cause having a VB run for these small stretches would be a waste of rake... instead of VB, they can make use of VB Metro (although limit is 200km, but can still run depending on the MPS of those particular trains' sections).... Shtbs' having distance more than 350kms can be thought of either having Shtb or VB rake....
