New Delhi: The per-kilometre construction cost of the proposed 220 kmph Sarkhej-Dholera semi high-speed double rail corridor, which was cleared by the government early this month, will be less than half that of the Delhi-Meerut Regional Rapid Transit System (RRTS), which has a design speed of 180 kmph, railway officials said.
On May 13, 2026, the Union Cabinet approved the construction of Indian Railways' first semi-high-speed corridor - a 134-km double-line rail project between Sarkhej (Ahmedabad) and Dholera in Gujarat - at an estimated cost of around Rs 20,667 crore.
