Rajdhani and Duronto
The Howrah–New Delhi Rajdhani Express covers the route in about 17h15m overnight — historically the gold standard for this corridor, and still a comfortable, reliable option in 2AC or 3AC, with catering included in the fare. The Duronto Express runs the same distance without commercial stops, but still ends up marginally slower than the Rajdhani in practice — worth knowing if you're comparing the two rather than assuming 'non-stop' automatically means 'fastest.'
Flying instead
A flight covers the roughly 1,300km air distance in about 2 to 2.5 hours, which is the obvious pick if your trip is short on days — but demand on this route means fares can swing widely depending on how far ahead you book.
Pro tip: Because this route is so heavily travelled, waitlist movement on the Rajdhani can be unpredictable during festival season — book as early in the ARP window as you can. See our guide to reading a WL number if your ticket is still waitlisted close to departure.
