THE Liverpool Turnback Project at the railway station is in its final stages.
The $160 million station upgrade will be fully operational by early next year.
The project was a part of the state government's Rail Clearways Program designed to improve capacity and reliability on the CityRail network.
Liverpool railway station services the Bankstown, south, inner-west and Cumberland train lines.
When completed, the project will include an additional platform and track to help passengers and trains through the station.
This aims to ensure services run on time and reduce delays.
There will also be more services able to terminate at the station in peak and some off-peak periods.
All platforms are accessible by lifts or stairs, and the overhead concourse and footbridge has also been extended.
Freight and country passenger services will also operate through the station.
A Transport for NSW spokesman said it would not be long until residents got all of the new services.
"Minor finishing work is taking place which includes testing to make sure that the new track and customer facilities will be fully operational in 2014," he said.
"The project will bring improvements to train service capacity and overall reliability to services at Liverpool station.
"All major work has been scheduled during planned rail shutdown periods to minimise the impact on customers."
