Japan Bullet Train

The high speed rail network is estimated to cost Rs 1.1 trillion including the purchase of 24 train sets, interest during construction and import duties

The N700s, the suffix stands for 'supreme', is the first new model of bullet train on Japan's busiest line for almost a decade.

If the train had continued to run, the crack could have caused it to derail in the worst-case scenario, transport officials said

The company is also developing a next-gen model which will be able to speed up to 500 Km per hour

Bullet-train passenger numbers at 340 million last financial year were more than three times the figure for domestic air travellers
