THE long-awaited £7 million makeover of Swansea's High Street station will be officially unveiled on Monday.
Work began on the scheme in September 2010. It followed years of criticism about its tired look.
Welsh Government Minister for Local Government and Communities Carl Sargeant will join senior figures from Arriva Trains and Network Rail in officially opening the revamp of the station, which originally dates to 1850.
The project has included installing new canopies over the platforms and a new canopy over the station's main entrance.
A glass screen wall has been built to cut draughts on the station concourse and allow light into the building.
Ticket barriers have been introduced as well as the construction of two new buildings inside the station's circulating area, including an information point.
Additional space has also been added for cyclists to store their bikes, a new ticket office built and the station frontage cleaned.
The work was said to have been crucial in sending out positive messages to visitors into the city.
Network Rail route managing director Mark Langman said: "The work to improve Swansea station is part of a series of improvements to the railways in South West Wales. The work will have a big impact on people's first impressions of Swansea and passengers will enjoy a much brighter and more comfortable station.
"Along with the Welsh Assembly Government, we are also carrying out work to redouble the line between Swansea and Gowerton, and rebuilding the Loughor viaduct, bringing the potential for more services to points west of Swansea and encouraging business growth across the region."
Ian Bullock, customer services director for Arriva Trains Wales, said: "We are delighted with the station's transformation as the 2.2 million passengers who travel through the station each year will now benefit from a bright, secure and more pleasant rail experience.
"The station is more spacious, has a fully accessible concourse with customer facilities, comfortable waiting rooms, digital information boards, a WHSmith and Costa."
National commercial property consultancy Lambert Smith Hampton (LSH) has played a significant part in the transformation of the railway station.
Darren Clarke, Regional Director for Property and Asset Management services at LSH, said: "We secured the necessary vacant possession of the station's original retail units let to WHSmith and Select Service Partner, trading as Pumpkin, to allow for the planned redevelopment.
"We then liaised with the appointed architects to ensure that the new retail units being created were fit for the intended uses following redevelopment."
