I guess, on Saturday, 12289 TATA - YPR was ahead of u.
12289 has Duvvada n Rajahmundry halt in between VSKP - BZA.
Where as 22807 has Samalkot, Rajahmundry n Tadepalligudem.
So, obviously, the late runner had to trail behind it and right behind, i guess, 12863 Howrah - Yesvantpur was trailing and must have overtaken AC Express which has led to...
more... further delay in arrival at Vijayawada. the on timers were allowed, and the late runner had to struggle.
