In terms of travel by Garib Rath, you will find it very comfortable. But you have to rent the bed roll @ Rs 20. Book it as soon as you board. There is Pantry service and the toilets are clean/cleaned well with soap and tissue paper available. Also there is running status displayed inside the coaches. Well, it's just like any other train with2/3AC except that you pay for the bed roll. It's a fully airconditioned train, and speeds are quite good, and generally on time. Good wishes.
