The SAR on Sunday said it is planning to use the Lo Wu Marshalling Yard as a storage facility to maintain a steady flow of supplies from the mainland to help battle the fifth wave of Covid infections.

The government said that a successful trial was conducted in the morning, together with the trade and the MTR, to test the operation of the complex near Lo Wu Station as a temporary railway freight yard.

"The government and the mainland authorities are having in-depth discussions on the detailed operation of railway cargo transportation," a government spokesman said in a statement.

He pointed out that both sides aim to conduct a trial run this week to "ensure its smooth operation".

The statement also noted that goods are being supplied to the territory via a water cargo transportation service that was launched on Friday, as well as truck services at various terminals.
