Glasgow's Central Station has one of the largest glass roofs in the world and now the glazing is about to have a £200,000 summer clean.
With 48,000 panes of glass to get shining, it is going to take about 20 weeks to complete.
Beginning next week, the project will be carried out by Glasgow-based company, SCS Group, which will provide 10 workers to scale the roof using walkways.
They will clean the entire outside of the roof, the panes above the station concourse and platforms, as well as the cathedral- like side windows, which are part of what is known as the Hielan'man's Umbrella above Argyle Street.
All the dirt and waste that has built up over the years, helped in part by the station's resident pigeons, will be scrubbed away to ensure it is sparkling clean in time for the Commonwealth Games in 2014.
