Up to 20 former Glasgow subway carriages have been put up for sale, with £5,000 price tags.<br /><br />The city's old-style trains were gradually taken out of service this year and replaced with new modern cars.<br /><br />It is hoped the carriages could be bought and reused in a variety of ways including as glamping pods, community hubs, cafes or even art galleries.<br /><br />Contractors Stadler Rail said the £5,000 sale price would cover the cost of scrappage. They have agreed to waive the fee for charities. Any un-sold carriages will be scrapped at the end of August.
