I dont find anything wrong in GT remaining ahead of Goa exp. Its arrival time at NZM is 6 am while latter has arrival time of 0625 am. Both are SF. Both have MPS of 110 kmph. P-7 doesnt mean that the train will run at greater speed than MPS. So nothing wrong in not allowing GOA to OT GT. Had the arrival time of GOA at NZM been before GT then it would hav been trolled.
