Rajdhani Express

The Rajdhani Express (lit. 'Capital Express') is a series of passenger train services in India operated by Indian Railways connecting the national capital New Delhi with the capitals or the largest cities of various states. Rajdhani, derived from the Sanskrit means "capital". Introduced in 1969, the trains are amongst the premium services operated by Indian Railways and regularly get a higher priority on the railway network.
In 1960, the Railway Board of India commissioned a study to increase the speed of its trains, which was restricted to 96 km/h (60 mph) on the existent broad gauge lines. A target of 160 km/h (99 mph) with an intermediate stage of 120 km/h (75 mph) was set for passenger trains. Research Design and Standards Organisation (RDSO) started work on the same in 1962 with field trials commencing in 1967. The coaches were manufactured by the Integral Coach Factory at Madras and hauled by diesel locomotives.
On 19 February 1969, the Government of India introduced a new express train capable of reaching speeds of up to 120 km/h (75 mph) as announced in the railway budget. On 1 March 1969, the first Rajdhani Express with nine coaches was flagged off from New Delhi to Howrah with the return journey commencing on 3 March. The train completed the 1,450 km (900 mi) trip in 17 hours 20 minutes and was the only such train in operation till 1972, when the second Rajdhani was introduced from Mumbai.
Rajdhani, derived from the Sanskrit means "capital" and later, with subsequent up-gradation of the tracks, new Rajdhani expresses were introduced connecting major cities with the capital New Delhi.
Rajdhani trains have fully air-conditioned coaches that have to be reserved in advance. While the trains initially had chair car coaches, now the trains exclusively have sleeper coaches in three configurations: first class, two-tier and three-tier. The first class has dedicated coupes, two-tier with open bays containing six berths per bay (four berths in two tiers and two on the side of the aisle) with curtains and three-tier with open bays containing eight berths per bay (six berths in two tiers and two berths on the side of the aisle). The coaches were exclusively manufactured by Integral Coach Factory at Chennai till 2006, when LHB coaches manufactured by Rail Coach Factory, Kapurthala were introduced. As of 2018, each train-set costs ₹75 crore (US$8.8 million). While the trains are capable of running at higher speeds, the maximum speed is often limited to 130 km/h (81 mph) with the fastest Rajdhani permitted to reach a maximum speed of 130 km/h (81 mph) and average speeds being much lesser due to traffic congestion and lack of supporting tracks. The Rajdhani express trains are usually hauled by WAP-7 electric locomotives.
The trains are amongst the premium services operated by Indian Railways and regularly gets a higher priority on the railway network. Passengers are served optional meals by Indian Railway Catering and Tourism Corporation (IRCTC), the menu of which could include morning tea, breakfast, lunch, high tea and dinner depending on the duration and timing.
