The $23 million Oatley station upgrade has been completed as work starts on improvements at Narwee station.
Oatley MP Mark Coure said the Narwee upgrade was scheduled to be finished within 18 months, and would include a week-long shutdown of the station in January.
Train travellers would be given plenty of warning on the shutdown dates, he said.
Mr Coure said work at Oatley was complete, “apart from some finishing touches”, including platform resurfacing, which would be carried out in January.
“In September we opened the new footbridge, stairs and two lifts which provide access to platforms one and two,” he said.
“A third lift is now operational, helping to make Oatley station fully accessible for less mobile customers.
“Work is complete on the western forecourt on Mulga Road, and customers can also again enter the station through the stairs on the River Road underpass.”
Mr Coure said, as well as access improvements, new accessible toilets and weather protection canopies had been added and the transport interchange upgraded.
“A new commuter car park with 100 spaces has also been delivered, along with four new accessible parking spaces,” he said.
The Narwee station upgrade is less challenging than that at Oatley because of the landform.
The eastern end of the island platform will be extended to provide new stairs, a lift and waiting area, which will be protected from the weather by new canopies.
The platform building will be refurbished with a new family accessible toilet, customer Information window and staff facilities to replace existing facilities in the ticket office, which will be demolished.
There will be improvements to bicycle facilities, including new shelters and additional bicycle racks.
A “kiss and ride” area, kerb ramps and bus shelter on Hannans Road will be provided and lighting and CCTV surveillance upgraded.
Transport for NSW rejected criticism during community consultation that the 18 months construction period was too long.
It said key construction activities, such as the erection of the temporary pedestrian access bridge, demolition of the ticket office and installation of the lift needed to be undertaken during scheduled closures of the tracks for maintenance.
“Around six rail possessions [shutdowns] over a period of around 18 months would be required to facilitate these and other construction activities,” it said.
Transport for NSW said an alternative plan was to reduce construction time to 12 months, but that would require the station being closed for six weeks.
