Reason:
1. Loco change @ MMR
2. Loco Reversal @ DD & Londa, while detachment of Loco (@ Rear for VSG Side) & attachment of different Loco (@ Front @ VSG Side) @ Pune
3. Pune to Vasco full of Ghat Sections, which make the train crawl, severely affecting Avg Speed
PS:...
more... Kindly note the AVG Speed in between NZM-MMR/DD, which will be quite high!!
