The Government has proposed seven new high-speed rail (bullet train) corridors to widen India's high-speed network. The proposed routes are Mumbai–Pune, Pune–Hyderabad, Hyderabad–Bengaluru, Hyderabad–Chennai, Bengaluru–Chennai, Delhi–Varanasi and Varanasi–Siliguri. Two of the corridors would connect Chennai, bringing Tamil Nadu's capital into the planned high-speed rail map alongside major cities of the south, west and north of the country.
