A team of retirees have already begun repairs on the heritage sign, and they will be working to return it to the way it was more than 90 years ago.

The project is run by the 2WG building's strata residents, who secured a $4000 heritage grant from Wagga council to go towards the repair bill.

The idea was spearheaded by Janet Bowen, who said many locals had nostalgic memories associated with the old 2WG sign.

"It's an icon for the town, it flashed away for many a year, and a lot of people remember it," Ms Bowen said.

"We thought it would be nice to get it going again."

The project will be a labour of love for Jan Hay and her husband Brian Hay, who will be doing much of the repairs painstakingly by hand.

Mrs Hay still has fond memories of walking past the sign as a young girl and tuning into the station from her farm outside Wagga.

She says many of her friends have grown attached to the old sign, which is what inspired the strata residents to take action.

"The sign is not for us, it's for the people of Wagga," Mrs Hay said.

The sign has rusted and turned a reddish white from age, but when the repairs are complete it will go back to its original green colour and will glow neon during the night.

The repairs are expected to take many months, but when the finishing touches are complete it will be returned to its rightful place on top of the old radio building near the Wollundry Lagoon Fitzmaurice Street bridge.
