While I was tracking this train yesterday, it crossed karchana at 23:06 while 12393 was at bdl at same time. (Gap of 84 kms) but then also somehow 12393 managed to ot it in ald- cnb section and reached cnb first and from there it has maintained the gap. This has become a daily affair now. People are paying surged price for this type of punctuality when it is being humiliated every time in its journey. Neither ER is concerned about its punctuality nor the controller.
On a lighter note (pls don't take it seriously) surge price should be introduced in 12393
