India’s first bullet train faces delays and tensions with Japan

India and Japan agreed to build a 508-kilometre high-speed rail line more than a decade ago.

It has not carried passengers, and its estimated cost has risen sharply.

Japan has objected to India awarding a signalling contract to German company Siemens, while India says decisions were discussed and agreed.

The dispute matters because it could affect the project’s progress and India’s plans to expand high-speed rail.
