In pictures: Canton train depot in Cardiff, South Wales

Here's a set of behind the scenes pictures from Arriva Trains Wales’ maintenance depot in Canton, Cardiff. 

The depot is open 24 hours a day, 365 days a year and the youngest train in the fleet is 16 years old.

I spent the evening there photographing the staff at work for a feature for the Western Mail newspaper.
