See the fact:
1. The main blog owner's train takes 30 hrs (55 kmph avg) from BGP to ASR whereas the red flag giver's train takes 29 hrs (57 kmph avg) so it doesn't make much difference
2. The main blog owner's train takes 29 hrs 30 mins (56 kmph avg) from ASR to BGP. The red flag giver has mentioned the timings in purpose of the train so calculating from there...
Distance:...
more... 1655 km
Time Taken: 29 hrs
Speed: 57 kmph avg
Again not much difference
