My analysis on TN schedule:
+++++++++++++++++++++++
TN has been speeded up by SR/SCR/CR in both directions.
WCR/NCR/NR schedule would get a change once the new TT comes in to effect.
At present AP takes 8...
more... Hrs 55 Mins from BPL to NDLS
Kerala take 9 Hrs 20 Mins from BPL to NDLS
Considering TN/TEL/KK gets similar duration between BPL to NDLS, TN would reach NDLS around 05:30 AM.
12622 may start at around11:00 PM and reach MAS at 06:15 AM.
We need to wait and watch IR has in store for these 3 trains.
