On holiday last year we walked down part of an old railway line and I took a photo of a bridge. The brickwork seems in very good condition considering it's 40 years since the line closed, but I expect it has had some maintenance to keep the bridge safe for walkers. Looking at this bridge I can't help imagining the wooden railings being removed and a small narrow gauge steam train running across it. Walking down the line I realised that all the trees must have grown since the line was closed, probably most of them in the first few years. It's interesting to see how quickly nature recolonises.
