The City and Industrial Development Corporation of Maharashtra (CIDCO) was appointed as a New Town Development Authority in 1970. The government acquired land from 95 villages and handed it over to CIDCO for the development of towns. To decongest the mother city, Mumbai, CIDCO developed 14 nodes in Navi Mumbai. The development of Navi Mumbai International Airport and 6 railway corridors in Navi Mumbai were meant to increase connectivity between the towns, nodes and mega establishments. The major features of the rail corridor are direct access from residential areas to the railway stations by foot, convenient interchange facility from one corridor to another, double discharge platforms at every station, easy-to-follow routes and comfortable and pleasant journeys from the key features of the commuter railway system in Navi Mumbai.

For that purpose, The railway Project between Belapur- and Nerul-Seawood-Uran was approved by Ministry of Railways and the CIDCO Board. The work on the project began in July 1997. However, due to various unforeseen reasons, the work was delayed and hence stalled, until recently when the project was revived after the tripartite agreement between Railways, CIDCO and Govt. of Maharashtra was executed on 29 July 2011.^[5][6][7]

The original estimated cost for the project was ₹495 crore (equivalent to ₹25 billion or US$300 million in 2023) in 1997, which escalated to ₹1,782 crore.^[8] The cost is shared by CIDCO and the Indian Railways (67:33).^[9]

Construction of Phase-I on this route was begun in the first week of March 2017. After completion of Phase-I, it was commissioned by CRS on 1 November 2018^[10] and after, was inaugurated on 11 November 2018 through video conferencing by Railway Minister Piyush Goyal and Chief Minister of Maharashtra Devendra Fadnavis.^[11] More than 3000 tickets were sold, with earnings of ₹90,000 (US$1,100) during inauguration day of Phase-I.^[12]
