Adding to it:
Toilets in 2A were nice with carpets and all.
Dustbins were regularly emptied and water refilling was done at all major stations.
Towel was provided to everyone.
Coach was...
more... new when I travelled so no flatwheel while railfanning.
We didn't got HOG loco so generator noise was there throughout the journey.
I did a short journey in RMM-BSB Express and the NER maintenance is not upto mark compared to SR.
