Despite the postponed Olympics, Japan is still introducing a new high-speed train that the country intended to roll out for the 2020 Tokyo games. The new train can go 224 miles per hour, but will be capped at “just” 177 for operation. The makers also say the train is earthquake-proof because of its onboard power source and different modes for tackling dangerous track.

Completed in 1965, the dam, made of compacted earth, was designed to hold 195,000 cubic metres of water, enough to fill 78 Olympic-size swimming pools and meet the irrigation needs of Shazixi’s farmers.

On a visit to the reservoir in mid-July, Reuters found the length of the dam, of about 100 metres, had largely vanished. It was reinforced 25 years ago…
