"How fast is this train?" is one of the most-searched travel questions. Here's a look at India's quickest trains and the world's record-holders — and how to check your own train's live speed.

Operating speeds differ from design/top speeds. Trains often run slower than their maximum because of track, signalling and safety limits.

India's fastest trains

Actual speeds depend heavily on the route — trains slow for curves, stations and track conditions, so you'll rarely sit at the maximum the whole way.

Design speed vs what you actually experience

A train's headline "top speed" is usually its design or test maximum. Day to day, it runs at a lower operating speed set by the track, signalling and timetable. That's why your journey feels slower than the record figures.
