Construction hardships

BUILDING high-speed railway lines in coastal areas, such as the Shanghai-Hangzhou route, is as hard as "constructing railways on soft bean curds" because of the regional geological situation, rail officials said.

But modern technologies used along the new route mean engineers are confident in the safety of the lines.

Wang Feng, deputy director of the Shanghai Railway Bureau, compared the railway projects constructed in Yangtze River Delta region with the high-altitude rail on Qinghai-Tibet route.

"The high-altitude railway is built on iced bean curds while here the lines are built on soft ones."

Similar situations also occurred when building the Shanghai-Nanjing high-speed line, which went into operation in July.

Hundreds of thousands of supports had to be laid along the route to make the foundations solid, experts said.

The new-generation bullet train on the Shanghai-Hangzhou track once reached a top speed of 416 kilometers per hour in a test run, breaking the world record.

But due to safety concerns, trains will travel at maximum speeds of 350km/h.

Despite the speed of the trains, a bottle placed upside down on the driver's instrument panel remained steady while the train was moving.
