This express seriously needs some attention, but then I was told, most of the long distance trains are like this only. Totally not impressive about this journey. Staff was ignorant. Food also i tried was not so impressive neither seemed hygiene. Train was moving slow. And it was boring journey for me. Last time I had travelled in Rajdhani, and in front of it, this experience is nowhere in the competition. Not suggested.
The only fastest train from Mumbai to Kolkata and it takes 26 hours with no stoppages so the passengers getting in and getting out is not there so no disturbance at all. In-house catering by IRCTC and bedding and towel are provided by IRCTC and is a boon for business traveller.
The train is normally on time. There is III AC and II AC which are quite comfortable and it passes through Nagpur but as there is no stoppages the train doesn't stop. The catering is good but still would prefer to carry home made stuff and fruits.
Duranto Express is the best train to travel from Mumbai to Kolkata and it gives you haste less journey with very less stoppages. The coach and seats were quite comfortable and IRCTC had given very good service. Coach, toilets and dustbins were clean and coach attendants were very helpful.
