Contractors Galliford Try finished laying the foundations in February, following the demolition of the former British Transport Police building, and a small section of the current station building next to Platform 1.
The roof is now water tight, the ground floor and first floor slabs have been fitted, and work has begun on installing the external cladding on the building.
Work has also started on the ground floor and first floor partitions, installation of internal services and the windows are due to be fitted.
It is all part of delivering a £150 million transport hub to provide an attractive commercial gateway to those entering the city by national rail, bus or tram.
As there will be no changes to the platform areas as part of the scheme, this has allowed it to be cleverly designed in two phases to ensure train services from City of Wolverhampton continue to operate as normal throughout.
The first section of the new station building is expected to become operational to customers later this year, when phase 2 of the programme – bringing down the remainder of the current station building and completing the new build - will also start.
The new state-of-the-art railway station building to serve the city will be fully open in summer 2020.
Wolverhampton Interchange Partnership consists of City of Wolverhampton Council (CWC), Ion, West Midlands Combined Authority (WMCA), West Midlands Trains, Virgin Trains, Network Rail, Midland Metro Alliance, Canal & River Trust, and Black Country LEP.
City of Wolverhampton Council Leader, Councillor Ian Brookfield, said: “A lot of hard work has been put in by all the partners on the Interchange scheme and it is heartening for everyone in the city to see the vision of the new railway station becoming a reality.
“There is more than £4.4 billion of investment on site or in the pipeline across the city, and the railway station development is a big part of how we are re-imagining and re-inventing our city centre."
Once work on the new station building is completed it will pave the way for the Midland Metro Alliance to begin the final link of the new city centre tram extension. The Midland Metro Alliance is currently delivering the Pipers Row and Railway Drive phases of the extension to the railway station.
