Post extension of Sealdah–New Delhi Duronto to Bikaner, this train is currently the fastest Duronto Express in Indian Railways. Most of the other Duronto trains take less travel time than their Rajdhani counterparts.

The Rajdhani Express gets top-most priority on the route, making it the fastest train in the Mumbai–Delhi route. But, the Rajdhani continues to be the fastest as both trains cover the same distance and  despite being non-stop service, with no commercial halts, the Duronto takes 40–70 mins more than the Rajdhani.
