Regarding the 22221 run, I feel NK to JL in 2 hrs. 19 mts is a tad too aggressive, 2.5 hrs sounds more attainable. I feel more comfortable with IGP, NK and JL times as :
IGP 17:12/14
NK 17:48/50
JL 20:19/21
Since...
more... the Durontos do CSMT-IGP in 2 hrs 10 mts, 2 hrs. 32 mts for this train seems too lethargic.
