Saw this on RailChat - http://www.railspatial.co.uk/map.html All you need to do is click on a railway line and a red pin thing will appear then when you put the mouse on it a small photo of that piece of track appears.
You can then right click the image for a slightly larger version, for example: http://www.railspatial.co.uk/getimage?elr=BML1&trid=1100&mileage= 33.0400
