Tickets went on sale in Hong Kong on Tuesday for high-speed rail destinations across Guangdong, with services further afield than Shenzhen and Guangzhou set to resume in phases from March 11.

At West Kowloon Station, one man told RTHK he had been forced to turn up in person to buy a ticket to Puning, because he couldn't get the MTR's high-speed rail app to work.

"When I tried to buy my ticket on the app, I couldn't see the departure date and time of the trains on it, so I'm forced to come to West Kowloon Station to buy it," said the man surnamed Yiu.

A man surnamed Wong complained that he couldn't buy a ticket to Shenzhen North either online or from a machine at the station, because he doesn't have a credit card.

"I couldn't pay on the mainland's railway website because I don't have a credit card. But when I tried to buy it at the West Kowloon Station's ticket machine, they do not accept Octopus payment," he said.

A woman at the station, meanwhile, was unhappy that she could not book a seat to Fuzhou in April because tickets are only available up to 14 days in advance.
