Express trains are express rail services of India. Express trains make a small number of stops, unlike ordinary passenger or local trains. Because of their limited stops, these trains are able to obtain the highest speeds of any trains in India. An express train is one where the average speed, excluding halts, is greater than 42 km/h. Including halts the average speed often is below 42 km/h. Although this is pretty slow as compared to international standards, the "Express" trains here mean faster than the ordinary passenger and local trains. In some cases, trains run express where there is an overlapping passenger train service available, and run as passenger train, where there is no supplemental passenger service.
