The RapidX is a rapid rail system operated by the National Capital Region Transport Corporation (NCRTC) in India's National Capital Region (NCR). RapidX is India's first regional rapid transit system and it has been envisioned to replace the conventional non-air-conditioned MEMU-operated local train network with a rapid rail system. The semi-high-speed trainsets operating on RapidX have an average speed of 100 km/h (62 mph).
Germany’s Deutsche Bahn won the contract to operate and maintain the entire Delhi–Meerut rapid rail transit corridor for 12 years, with a bid valued at approximately ₹1,500 crores (roughly US$178 million).
