Commuters can now take advantage of extra free parking at Four Oaks railway station with the opening of a new £2 million Park and Ride extension.
Centro, the region's public transport delivery body, has completed the work in just under four months, increasing Park and Ride capacity at the station by almost a fifth.
The scheme, which built a steel framed single-deck car park over one of the existing car parks, added 55 more spaces to the existing 275 at the busy station near Sutton Coldfield.
The aim is to ease overcrowding at the Park and Ride facility - which proved so popular with commuters that it filled up well before the end of the morning rush hour.
Coun Kath Hartley, vice chairman of the region's transport delivery committee, said: "The free parking spaces we provide at Four Oaks and other stations across the West Midlands have been hugely successful in attracting thousands of motorists to make the bulk of their daily commute by train.
"Park and Ride is extremely popular and spaces get snapped up very quickly each day."
The extra spaces will also help combat congestion and carbon emissions by taking a further 32,000 commuter car journeys off local roads each year.
The scheme also included installation of low energy lighting, CCTV cameras and help points linked to the Network Safety and Security Centre.
Centro and its partners have invested more than £15 million in Park and Ride facilities since 1997 to provide more than 8,000 free spaces at 38 rail stations and three Midland Metro stops across the region.
These spaces are calculated to take more than three million journeys off the region's roads each year.
