Sampark and Kranti are borrowed from Sanskrit, . Sampark(Devanagari:-सम्पर्क) means Contact and Kranti(Devanagari:-क्रान्ति ) means Revolution. The name denotes a revolutionary step taken by Indian Railways to provide high speed connectivity with the National Capital to the common man in form of non-air conditioned express trains with minimal stoppages and high running speed. Earlier such a facility was available on the Rajdhani series of super-fast trains which were completely air-conditioned and hence quite expensive. The Rajdhani and Shatabdi series are the fastest trains in India. The Sampark Kranti trains run at a slightly lesser speed than these and yet provide for a high speed option at a normal price due to the minimal stoppages and relatively faster speeds than other non-Rajdhani and non-Shatabdi express trains.
