The Airport Express will extend its service to 3:45am on Monday due to a high number of passengers expected to arrive in Hong Kong after a typhoon.

Ben Lui, MTR's chief of airport segment, said six additional trains will be deployed from 1:15am for travellers to get to Tsing Yi, Kowloon Station and Hong Kong Station.

They will run every 30 minutes.

The rail operator said it expects many travellers to arrive in Hong Kong following the resumption of flights disrupted by Typhoon Wipha earlier.

Lui also pointed out that all MTR lines would have stopped running by the time the passengers reach the urban areas.

"If the passengers do not the transportation to their destinations, our staff will provide seats, charging facilities, as well as food and water supplies, so they can stay at a safe place," he said.
