Travellers should pick Jagganath Puri Express from Howrah because it is a night train and you will reach Puri in the morning. No need to carry any food. I travelled in 3 tier A/C. The seats were comfortable. As it is a night train so no great views. All you have to do is board the train and go to sleep and when you get up you reach Puri. The toilets were clean and the bedding provided were also clean. Those who wish to go to Puri can surely opt for this train.
