This tip is based on my couple of journeys between Ahmedabad and Mumbai.
1. Tickets and availability: Even in the peak season, this is a train on which you can bank on. I traveled during the Christmas season and was successful in getting the tickets. The main advantage and disadvantage of this train are its timing at ADI. It arrives at ADI at a very odd time of 1:10 AM in the night due to which many people avoid it and making it available for others.
2. Coaches and Comfort: During my entire
journey of 6h 40m, I didn't sleep for a minute. All credit goes to the coaches which give you heavy vibrations and jerks. A couple of times in the night, I felt the train has derailed due to the jerks. If you are looking for comfort, please don't book this train. I was on the lower berth once and side upper berth the second time. Lower berth journey was really unpleasant.
3. Speed: "Blaster" is the word that comes to my mind when I think of my experience travelling in this train. After leaving Ahmedabad, it literally traverses as a rocket blasting through stations. Being a railfan, this is one thing all of us crave for but at night, even railfans require comfortable sleep which is largely disturbed by the blasting speed and coach geometry. Speed is one department where this train doesn't disappoint at all. Continuously hits the 100 km/h mark.
