It wasn't hard to find this eye-catching collection of cess pictures - the railway is littered with loathsome linesides. We'll keep our eyes peeled for other purlers as we tour the network and if you have any photos which tell a similar story, email them to us and they'll be featured here.
And it's not just the big stuff. Short lengths of rail, discarded fishplates and loose troughing lids are a magnet for vandals. And there's plenty of ammunition at Doncaster (left) and Ardsley.
