It is one of the three Namo Bharat corridors planned under Phase 1 of the Rapid Rail Transport System of the National Capital Region Transport Corporation (NCRTC).

The corridor has been planned for dual use, accommodating both Regional Rapid Transit System (RRTS) services for longer-distance travel with fewer stops and metro services for shorter suburban travel with more frequent stops. The project's cost estimated in 2017 was 37,000 crores (; or US$ billion).

History As part of the Integrated Transportation Plan 2032, the National Capital Region Planning Board (NCRPB) identified eight rail-based rapid transit corridors to improve the efficacy of transportation system in the NCR. These were: Delhi - Gurgaon - Rewari - Alwar Delhi - Ghaziabad - Meerut Delhi - Sonipat - Panipat Delhi - Faridabad - Ballabhgarh - Palwal Delhi - Bahadurgarh - Rohtak Delhi - Shahadra - Baraut Ghaziabad - Khurja Ghaziabad - Hapur Of the aforesaid corridors, Delhi-Alwar, Delhi-Panipat and Delhi-Meerut are to be constructed in the first phase. The Urban Mass Transit Company was commissioned to conduct a feasibility study on 23 March 2010. The study thus submitted was approved by the Planning Board in 2012. The contract was then transferred to NCRTC on 18 January 2017 to carry the study forward.

On 15 June 2018, the first phase of the project, a long segment from Hazrat Nizamuddin to Shahjahanpur-Neemrana-Behror, slated to cost an estimated 25,000 crore (; or US$ billion), was approved by the Haryana government.

Construction Construction of the Delhi-Alwar RRTS is likely to commence from August 2026, lasting until November 2031.
