The new £6m St Helens Central Station is due to open by the end of August.
The striking Pilkington's glass-fronted building was designed by architect SBS of Manchester to complement the nearby George Street conservation area.
A spokesman for SBS said: "The station has been designed as an iconic gateway into the town, equally impressive when you approach it by rail or road.
"The copper cladding has been specially treated to retain its colour and was used because it is both extremely resilient and sustainable having an extremely long life. It also requires little maintenance."
Funding for the station came from Merseytravel, local partnership St Helens Together and the European Objective One programme. Northern Rail, St Helen's Council, and English Partnerships are also supporting the transformation.
The works are being managed by Network Rail on behalf of Merseytravel.
The remade station will include a new booking and ticket office, improved waiting areas on both platforms, 120 park-and-ride spaces, including dedicated bays for blue badge holders, new lifts, cycle parking, digital CCTV and new customer information systems.
