Vande Bharat Express, India's first semi high-speed train, has been plagued by several-issues since its trial-runs began in November last-year. From technical-snags to cattle hurdles, country's first engine-less train, manufactured by Integral Coach Factory, Chennai, continues to run into trouble almost every day. Multiple delays and glitches have triggered a political war with Congress president Rahul Gandhi targeting the government and mocking PM Modi.

The Chinese government has approved a project to build the first underwater bullet train route in the country, a source said. The line will connect Ningbo, a port city south of Shanghai, to Zhoushan, an archipelago off the east-coast. The proposed underwater tunnel will be a part of the 77-km Yong-Zhou Railway plan to boost tourism and create a two-hour-commute zone within Zhejiang province.

Japan's first driverless bullet train maglev, which is capable of clocking a speed of 500 km/hr while running 10 cm above the ground, was developed keeping in mind the country's domestic requirements and not in competition with China, its developer has said. Touted as the future of public transport across the globe, maglev will be unveiled in Japan by 2027.
