The work got under way in December and included the repair of the sandstone exterior of the station building and platforms.

"The sandstone was lime washed while the existing ochre coloured wall paint was cleaned and moss was also removed from the roof," Member for Bathurst Paul Toole said.

"Custom-made lead flashing was also used to protect the parapet and windowsills.

"As well, the station's original chimneys were replicated in keeping with this original heritage-listed building that opened in 1876."

Specialist local trades that have been involved in the work include a heritage architect, structural engineer, stonemasons using sandstone quarried in the Southern Highlands, and a local apiarist who relocated a beehive from inside one of the chimneys.

"Bathurst residents have immense pride in their historical buildings, so it's exciting to see the upgrade of one of our town's greatest landmarks cross the finish line," Mr Toole said.

Sydney Trains chief executive Matt Longland said railway heritage and restoring local landmarks to their former glory was important to the organisation.

"Across NSW, we have restored and preserved historic railway buildings to help celebrate the history of the railways and attract visitors to our services and the communities we serve," he said.

NSW TrainLink chief executive Pete Allaway said he welcomed the completion of the upgrade.

"Railway buildings have historically played a major role in the communities we serve, often taking pride of place in towns big and small," he said.

"We're delighted to see this restoration complete and I know our customers and staff will also be impressed by this work."

The work was funded through a $790,000 investment from the NSW Government, through the Sydney Trains Major Periodical Maintenance Program.
