The creation of Museum Park, officially opened on October 1, and surrounding areas has delivered a $5 million boost to the local economy and provided 300 construction jobs, Taylor Martin, Liberal member of the NSW Upper House for the Hunter, said.

He added that the new park was a great example of the NSW Government's $650 million commitment to revitalising Newcastle's CBD.

"Newcastle is a really exciting place to be right now with great public open spaces popping up right across the city," Mr Martin said.

"The community has played a big role in the creation of this park through extensive consultation and it's wonderful to be here today to see our shared vision come to life."

Planning and Public Spaces Minister Rob Stokes said the new park is a demonstration of Newcastle's resilience and ability to continually reinvent itself.

"Site by site, the former rail corridors are making way for high quality green and public spaces for the community to relax, right in the centre of the CBD," Mr Stokes said.

"This fantastic new public space will also make it easier for people to get around with new walkways that connect the city centre to the waterfront and the exciting Honeysuckle precinct."

The old station building has been restored and renovated and will house a new visitor information centre from early 2020.
