MTR officials have warned that services on the Tung Chung Line are expected to be curtailed late on Saturday night, with no trains travelling between Tung Chung and Sunny Bay.

Free shuttle buses will be provided for people to travel between the two stations as major track diversion works take place as part of the Tung Chung Line extension in the two hours before the line's usual closure time.

The railway company said the last train from Tung Chung will depart at 11.01pm, while the last train going all the way to Tung Chung will leave Hong Kong Station at 11.07pm.

Trains from Hong Kong to Sunny Bay and vice-versa will run as usual.

The company’s chief of airport segment, Ben Lui, said services might also be affected on Sunday if there is any delay to the works.

“We have done a lot of preparation and planning, and our team will work closely together. Hopefully, we will have all the works completed before the next traffic day,” he said.

“We will try our best, and strive for the early completion of the works, without affecting train services on the next day.”

With a tropical cyclone expected to move closer to Hong Kong, the works may be postponed to the following Saturday if the weather is too bad, Lui said.
