I am right now travelling by this train. Very small number of passengers. No water in my coach.
There is no catering like they have in 12679/12680.Some samosa, tea, water and tomato soup sellers got in at KPD, sold and got down at JTJ when the train slowed down. One vendor even wore typical IRCTC authorised vendor's checked shirt.
Since the stops are only for 2 minutes at KPD, SA, ED and TUP, it is advisable to carry own food and water from MAS itself, unless one does not mind the food/beverages from...
more... station vendors.
I am not sure what may be in store for dinner. I am writing this before train would reach SA.
