I and my brother went to Kerala last month. We decided to to go by train. Actually, all train tickets were full only the Kerala express was available so we booked AC 3 tire ticket for us.
The Kerala express was coming late to CST station. When we board a train our berth was so dirty and some smell came.
Then we report to the staff then they came and starts cleaning. The pantry car is available on the train. The various verity of food was available for breakfast, Lunch, and dinner.
But the quality of the food was not so good the price was also high.
The train is available daily dont worry about that. The Kerala Express having on board facility.
The train was reached at the destination 30min early. We were happy for that.
