Everyone knows if a train is running late, ONLY RailFans know WHY it is late

This train should be returned back to its original timing of Pre-Covid times . Almost every day this train leaves SMVT 2 hours late due to delay in incoming of 12863 . As a result this train reaches Howrah at odd hours of night like 1am or 2am . This is becoming a regular affair . SER should look at change the timing to evening departure . In addition we have multiple trains leaving at the same time before 12 noon from BLR . Changing the departure to late evening will surely be welcome by frequent travelers on this train . If rake shunting is a problem in Bangalore then how was it managed previously ?
