Rajdhani Express was introduced in 1969 for providing high-speed connections (up to 140 km/h / 87 mph, speed varies depending upon the particular track section) from various railway stations in the capital city of New Delhi to the capital cities of various states in India (or, in certain cases, prominent cities within the state the train serves).
These trains have higher priorities on the Indian railway network and are fully air-conditioned. The passengers are provided with complimentary meals during the journey. Depending on the timings of the train, lunch, high tea, dinner, morning tea and breakfast are served.
