I and my friends were decided to go by Dehradun Rajdhani express. We board the train at Madurai railway station.
In comfort point of view, the train was not so clean and the bad smell comes from the toilet. We took the food from the Madurai railway station.
The quality of the food was average. We booked 3tier AC ticket for both of us me and my friend. Luckily we got the same berth. The berth was not so clean and windows also not proper.
The train tickets are not available normally for we have to reserve it list one week before. The train is available most of the days there are fewer chances to cancel the train.
In case of the train canceled then the ticket money will get the refund. The train has a on board facility.
