I can see that the reason for not giving OT is, 18463 can't recover the delay I guess after GNT. But, for 12863, I guess the delay at VSKP is still maintained at RU. I guess, that's what SCR will look in to. They don't delay trains more in their section while hand over. I expected 18463 before time at BZA, but it reached at 19:10 only.
