The interiors of Trivandrum- Calicut Jan Shatabdi.
The food was great though the options were limited, atleast till ERN, unlike the other JS where I had seen variety. The speed was OK, we were a little late. The seats in normal CC are not so comfortable, I don't know how is the AC Chair Car, maybe I will travel in it later.
Anyway this train is good enough for a 4.2 out of 5 points.
