The new-look old gold and black station opened to visitors in May after phase one of the project was completed as part of a £150 million transport scheme.
Now contractors have made “good progress” toward the milestone of tearing down the old building, council chiefs have said.
Councillor Stephen Simkins, cabinet member for city economy, said: “The opening of phase one of the new railway station to the public has given everyone a taste of the final interchange vision.
"Working under strict Covid-19 safety guidelines, the contractors have made good progress on phase two demolition works at the station as we move towards the major milestone of bringing down the old main building.
“The completed interchange will connect train, tram and bus in one place and will ultimately provide a gateway to our city that we can all enjoy using – and be proud of.
“The railway station development is a big part of how we are re-imagining and re-inventing our city centre.” to help bring in further investment, which is critical now more than ever to our local economy and the creation of jobs, as we look to recover from the impact of Covid-19.”
The new station building is expected to be fully open next year.
