Carlisle station is expected to see lighter, brighter platforms because of work being done to the roof.
As part of the Great North Rail Project, Network Rail is investing £14.5m to extend the life of the roof, which dates back to 1847.
This will be done with safer, easier to maintain material which will brighten up the platforms with daylight.
The roof's metalwork is also being repainted and the main lighting above the platforms is being renewed.
Network Rail has worked closely with Virgin Trains, which manages the station, to plan the work and minimise the impact on the station and passengers as much as possible.
1,500 trains have continued to travel through the station as normal every week.
Carlisle's MP was given a tour of the work going on at the station and roof space:
The majority of the glass removed from the roof is being recycled by North West Recycling Ltd, based at Kingmoor Park, Carlisle.
Around 120 tonnes of glass has been removed from the roof and will be recycled into new new bottles and windows.
Work is due to be completed with all scaffolding removed by February 2018.
