It's funny where you find traces of long-lost railways, isn't it? Here's two images taken in the past few days while out and about in the Peak District. Sleeper fencing (with 3-bolt chair holes) and bullhead rail cattle grids (complete with fishplates) were found on a couple of farms. Good examples of recylced materials... and so easy to reproduce in miniature. Indeed, I don't recall ever seeing a cattle grid on a model railway layout.
