This is the moment rain pours through the roof of a Chinese train station during an epic storm making it look like it was raining inside the building.

The incident dubbed a 'water curtain cave', appeared on the high-speed rail platform during heavy rain in Wuchang, in Hubei province, in China, on June 21.

The footage shows bolts of lightning lighting up the building's windows while rain pours into the station from the roof.

Onlookers that the platform at Wuchang Station was like a 'water curtain cave'.

But the Wuchang Station reportedly claimed: 'The leaking part was a skylight reserved for lighting and ventilation. The rainwater flowed directly onto the rails and did not affect passengers.'
