Sahi kaha aapne ..Sk doesn't need to be more than 1 hr early....just utilise that time for trains which have arrival time before SK ...and any train shouldn't be overtaken by any train which have arrival time before at coming stations...than all trains will come on time ....
Today's by stopping all such non required overtakes ..SK managed to be on time @ ndls and rjpb ...
So it clearly shows ..that this controlling is best...
