Delhi–Alwar Regional Rapid Transit System. Delhi–Alwar Regional Rapid Transit System (Delhi–Alwar RRTS) is a 164 km long under-construction semi-high speed rail corridor connecting Delhi, Gurgaon, Rewari and Alwar. It is one of the three RapidX corridors planned under Phase-1 of the Rapid Rail Transport System of the National Capital Region Transport Corporation (NCRTC).
