The MTR said tickets for overnight high-speed trains between Shanghai, Beijing and Hong Kong would be available for sale from Wednesday noon.

The overnight trains would operate between Shanghai, Beijing and West Kowloon Station from June 15 from Fridays to Mondays.

The MTR said tickets would be available from Wednesday noon on the mainland's 12306 ticketing website or mobile app, and at ticket counters.

Fares for one-way trips between Hong Kong and Beijing would be approximately between HK$937 and HK$1,448, while those between Hong Kong and Shanghai would be approximately between HK$682 and HK$2,128.

Transport minister Lam Sai-hung welcomed the new arrangements which enhanced the services provided by the Hong Kong section of the express rail link.

"The new sleeper trains...tailored to meet the passenger needs and provide them with a more convenient, comfortable and high-quality cross-boundary rail service, enhancing the travel experience for both business and leisure passengers," he wrote in a statement.

A Beijing resident said the new arrangement further encouraged him to visit Hong Kong one day.

"I don't like to travel by plane, so if high-speed trains have sleeping coaches, I won't feel tired even it's a long trip," he told RTHK.

A tourist, who's visiting Hong Kong, said she could manage time better if she travelled by high-speed trains.

"Due to weather conditions these days, the situation of flight delays is very serious. My flight was delayed for almost eight hours, so travelling by high-speed trains may be more convenient," she said.
