The new platforms will first come into operation on June 20.
They were at the centre of a shoddy work scandal in 2018, when media reports revealed how contractors had cut corners by shortening steel reinforcement bars.
A government-appointed inquiry subsequently found “serious deficiencies” in the management of the project, even though it concluded that the structures were safe.
One woman told RTHK that she was worried about the station’s safety.
“I live in Yuen Long. I have no choice…They have given the [investigation] report but I hope they will increase the transparency to the public,” she said.
Speaking during a media tour of the station, the rail firm’s chief of operating, Sammy Wong, stressed that the necessary checks have been completed, with statutory approval obtained to ensure safety.
He added that measures will be taken to make sure passengers know where to go when the new platforms come into service.
“Passengers need some time to get used to it. However the whole arrangement, in terms of the movement of passengers as well as all those measures, like the provision of signage, information and staff assistance, the interchange arrangement will be smooth on day one,” he said.
Wong added that around 230 staff will be deployed to help passengers.
