Naini
Naini (also known as Naini Industrial Area) is a satellite neighborhood and a twin city of Prayagraj in Prayagraj district, Uttar Pradesh, India. By the 1950s Naini was established as the chief industrial area of the city. History
Naini had a prison, Naini Central Prison, where many, including Pt. Jawahar Lal Nehru, the first Prime Minister of India—were imprisoned during the Indian independence movement. The first official Airmail flight in the world arrived in Naini from Prayagraj. Henri Pequet carried 6,500 letters a distance of 13 km. This was the first commercial civil aviation flight in India.

Transport

Naini is connected to Prayagraj via two bridges over the river Yamuna. The older one, Old Naini Bridge built in 1927, is a two lane bridge. The new one, New Yamuna Bridge was completed in 2004. NH-2 joins the Naini to Rewa through Ghoorpur. Tempos, Bus and autos are the main mode of travel in Naini-Prayagraj. This route doesn't have a very frequent local bus service, but recently, UPSRTC has launched the city bus services, making easier the public transportation from Naini to other nearby places, including heart of the city. Apart from Naini Railway, Cheoki station is also used, but mainly it is used for transporting goods. However, in recent times, Cheoki railway station has started to become more important as many of the trains are getting their schedule changed where in it is replacing Prayagraj Junction itself.
