Here's one of those things I've always been meaning to ask but never have actually got round to doing it:
What is the purpose of the zone signs at stations eg "Blue Zone", "Purple Zone", "Orange Zone" - also what do the big signs saying OFF mean?
I'll probably find some more to ask about in the future, but Mr Google isn't playing ball when I search them so I figured the professionals here would know!!
