It's difficult to pick a single tip category for this train. Food, speed, bedding etc- everything is good. Probably the train with highest priority in this country.
Only two negative points from pessimistic view:
*Goes into WL very fast.
*To all apart from those who think that as this has LHB rake so it does not shake its waist or who are too optimistic...
more... not to see any negative in LHB coaches- jerking may be a problem just like in ICF, especially when at the highest speed and crossing track joints. Please do not stand within 2 feet from open door if not holding anything. You can fall outside.
So, ultimately, this train is not for railfans.
You will find it special to see too many staffs engaged serving only one train compared to other trains.
