New Delhi railway station
New Delhi railway station (station code: NDLS) is the main railway station of the Indian capital of New Delhi. Platform 1 is located at Paharganj and platform 16 opens up on to the side of Ajmeri Gate. The station is in Central Delhi, about  north of Connaught Place in New Delhi. It is one of the busiest railway stations in the country in terms of train frequency and passenger movement. Until the 1950s, the Old Delhi railway station was the main station in Delhi. The official inauguration of the one platform New Delhi railway station took place in 1956. The station building at Paharganj was the first in India to have common station facilities for all classes of passengers including a common entry and exit. With the station meeting its saturation limit as early as the 1970s, there have been continuous efforts over the decades to decongest the station including the rail traffic. By the 1980s the station had seven platforms, in 1995 it had ten platforms and during the 2010 redevelopment the platforms increased to sixteen. The new station building on the side of the Ajmeri Gate was upgraded during this redevelopment. Delhi Metro connectivity has been integrated. The 16 platforms cater to around 235 trains which start, end, or pass through the station daily. According to different studies and periods of the year estimates for daily footfall and passengers handled varies. The average daily passenger inflow and outflow is about 2.13 lakh (); other estimates place daily footfall at around 5 lakh, which can reach 6 lakh during peak festival season. Since 1999, the station holds the record for the largest route relay interlocking system in the world. As per the categorization of Indian Railway stations by commercial importance the station was formerly ranked A1 and is now an NSG-1 (Non-Suburban Grade-1) station. History

Before the new imperial capital New Delhi was established after 1911, the Old Delhi railway station served the entire city and the Agra–Delhi railway line cut through what is today called Lutyens' Delhi. The line ran through plans for a new capital, including space set aside for the All India War Memorial and Kingsway. The railway line was shifted along Yamuna river and opened in 1924. Minto rail bridge came up at this time. The East Indian Railway Company sanctioned the construction of a single story building and a single platform between Ajmeri Gate and Paharganj in 1926; this would go on to become the New Delhi railway station. The government's plans to have the new station built inside the Central Park of Connaught Place was rejected. The Viceroy entered the city through the new railway station during the inauguration of New Delhi in 1931. New structures were added to the railway station later and the original building served as the parcel office for many years. By 1955 a new station building had been constructed at a cost of about . A common entrance, exit and circulating area for all classes of passengers was created. It was the first station in India to have common facilities. Up until then an adapted form of the colonial era system had remained in place, the platform and area that had been reserved for the Britishers was used by upper class Indians while the other platforms and areas went to the lower classes. A common area for refreshments was built,  waiting areas as per ticket class, and resting rooms with different fees open to all classes. The building layout and design was done under the Architect of the Ministry of Railways. The one platform station was officially inaugurated on 16 April 1956. Up until then Old Delhi railway station was the main station. The building exterior at this time was made of exposed concrete. In preparation for the 1982 Asian Games, the exterior of the main entrance on Paharganj side was covered with sandstone. This was then painted in the 1990s. Before the 2010 Commonwealth Games the original exterior was covered with aluminum. Pillars and benches were also given a metal look. Subsequently the exterior aluminum panels were given a colour combination. In September 2009, the new building of the station on the Ajmeri Gate side was opened. The building has a total floor area of 9,000 m2 spread over three floors. The entrance and departure on this side were moved to different floors. A new route relay interlocking system was put into place; since 1999 this system remains the largest in the world according to Guinness World Records. The number of platforms was increased from 12 to 16 during this period. In the 1980s, the station had seven platforms. In 1995 the tenth platform was constructed. The Paharganj side faced more space constraints as compared to the Ajmeri Gate side. In 2007, architecture firm Farrells (along with others such as Arup and SMEC) were commissioned as consultants with regard to the redevelopment, modernisation and expansion of the station in time for the 2010 Commonwealth Games in Delhi. The consultants would also be involved in the masterplan of the Indian Railways for the station redevelopment. Other consultants included AREP, Gerkan, Marg and Partners, HOK group and Rail India Technical and Economic Service (Rites). In 2008, a set of diagrams emerged; one set consisted of a glass and steel domed exterior encasing the entire platform area of the station, extensive changes would be made to ensure optimal utilization of footfall and vehicle space, and commercialization was integrated. The station occupies  and 10–20% of it (50 acres) could be used for retail and commercial use. 13 consortiums from around the world showed interest. In March 2020, long-term plans for a public private partnership (PPP) to change the railway station to improve passenger flow was described, with the Rail Land Development Authority put in charge. The plans and timing are not firm, only the goal, to make a world-class railway station. There are around 8 temples and 5 mosques located in the vicinity of the station. There is a temple (Lankeshwar Mahadev temple) on platform 6-7 and a mosque (Masjid Ghareeb Shah) on platform 2-3. There was an unsuccessful attempt to demolish the temple in 1982. Ajmeri Gate and Ghaziuddin's Mosque are also located in the vicinity of the station. These structures come into question during redevelopment plans. The AMASR Act regulates construction in the vicinity of centrally protected monuments. Rail traffic 

The station is the main junction for the Rajdhani Express and a number of pairs of Shatabdi Express originate and terminate at this station.

Luxury tourist trains have itinerary's which start and end at New Delhi railway station, Palace on Wheels, Royal Rajasthan on Wheels and Maharajas' Express. The Buddhist circuit train Mahaparinirvan Express also starts and end at the station. The number of trains per platform per day varies from 13 trains to 23 trains. On average the station handles 237 trains every day, while the maximum handled in a day reaches 275. It handles around 350 unique trains in total. The station handled the introduction of passenger trains to cater to the increasing population growth and industrialization such as on the New Delhi-Ahmedabad route. Double heading trains ran from the station including the KK Express on the New Delhi-Bangalore-Trivandrum route.

In the 1980s the station handled around 100 trains daily, including coaching, mail and express trains. New Delhi railway station has seen numerous initiatives over the decades to decongest it. In the 1970-80s goods trains previously arriving at the station were diverted to other stations. New platforms including island platforms and platform faces were undertaken. Washing and stabling points, and shunting necks were increased. The Thomson Road side of the station also began to be developed with a station building, ticket facilities and other ancillary structures. Hazrat Nizamuddin railway station began to be considered with regard to easing the load of New Delhi railway station. In the 2000s decongestion efforts includes construction of new passenger terminals such as those at Anand Vihar Terminal railway station, diversion of trains to other stations such as Hazrat Nizamuddin railway station and additional stoppage of trains at other stations such as Delhi Shahdara Junction railway station. With the five main railway terminals in New Delhi, including New Delhi railway station, reaching a saturation limit other stations such as Bijwasan railway station are being developed. Lines 
Rail lines include the New Delhi-Mumbai main line, Howrah-Gaya-Delhi line, both part of the Diamond Quadrilateral, and the New Delhi-Chennai main line; the lines have been improved in various ways over the years and there are plans to further improve it. The maximum sectional speed permissible on these lines in 2016 was . The Delhi-Ahmedabad high-speed rail corridor, part of a larger modernisation push, is planned. Suburban
