What I've heard is that long distance trains, they get shunted to a yard for maintenance purposes and then head back... obviously not the case for short TATs... with the delay charts I'm seeing for Uday, hypothetically if departing at 630am from CBE, there'll be many trains going towards SBC, like the Brindavan and Shatabdi and other trains from different sources making use of the JTJ-SBC line.... with that there'll be chances of overtake(n) situations that can lead to delay arrival at SBC... continuing that, TAT is only 30mins btw Uday and SBC MAS DD... so if dept delay happens, then SBC MAS DD will get delayed because of overtake of the MYS MAS VB.... let me know if I might have mentioned any incorrect stmts... this is my thinking...ЁЯСНЁЯСН
