So, I was waiting for my train home tonight, and my mind was wandering and wondering:
The vast majority of platforms have a yellow line, behind which it is advised to stand behind to avoid being injured by passing trains, or even by lengthy ones that are arriving or departing. My question is- is there a set distance for the line? As I was waiting, I noticed that on my platform it was painted tight against the edge of the concrete slabs that form the (otherwise tarmaced) platform, whilst on the facing platform, it appeared to be a few inches away from it.
Is line speed taken into account? I've seen lines on some narrow platforms on 100mph lines that would be almost impossible to stand behind, especially if one is, um, larger. Also, near the end of island or terminal platforms, I've seen lines come together and then continue as a single line, which seems a bit daft...
So, what are the rules? Or is it left to the whim of the line painters, a judgement of what "seems right" and a bit of "artistic licence"?
