this train is very much available. dont get confused. it runs with the old duronto coaches of howrah-mumbai duronto. but it has stoppages in between. only ac accomodation though. 1ac, 2ac, 3ac, and 3ac economy is there. the rake belongs to SER and hence it takes the kharagpur-tata-bokaro-gaya route to delhi instead of the usual bardhaman-durgapur-gaya route. you can also find videos of this train in youtube
