Who are The Rail Authority? Is it just another name for Network Rail? I say this as I've always wondered who they are, some older bridge signs say to report to Railtrack in case of a bridge-bash (which might just be a tad problematic...), but the newer ones mention The Rail Authority, usually with a York number 'round these parts (ECM5). I can't find a website for this organisation, is there a separate authority that maintains bridges? I thought many were Network Rail's brief?
