The new glass-fronted train station building – which is double the size of the old building – will be fully open to the public from Sunday.
Along with the new building, there have been a number of improvements made to the forecourt area to make it safer for pedestrians to access the station and also to improve the drop-off, taxi and disabled parking arrangements.
Councillor Ken Pollock, Worcestershire County Council's cabinet member for economy and infrastructure, said: "It is great news that the new station building which is a huge asset to the area, will be open and ready for when the current restrictions begin to ease.
“The customer experience at the station will be vastly improved and the changes to the forecourt layout will make it much easier for pedestrians to access the building safely.
"I look forward to being part of a more official opening in the not too distant future.”
The improvement works have been mainly funded by Worcestershire Local Enterprise Partnership and Greater Birmingham and Solihull Local Enterprise Partnership via the Local Growth Fund, with contributions from Wyre Forest District Council and Worcestershire County Council.
Brenda Lawrence, head of stations for West Midlands Railway, added: “The new bigger and brighter Kidderminster station is a fantastic addition to the town and will offer our customers a much-improved travelling experience.
“At the moment, with government advice on social distancing still in place and limited capacity on board our services, we are asking our customers to only use the train for essential journeys where they have no other means of transport.”
An official opening of the new building is expected to be held later in the year, Worcestershire County Council has said.
