No yellow line at melksham.
Nor at Glasgow Central, it would seem from the photo. Tactile paving seems to be replacing yellow lines, or is that just low-speed stations?
Dim siarad Cymraeg? Yn Saesneg, Barmouth Bridge.
Is siarad the way you spell the word which I believe is pronounced 'sharad' and translates as 'speak'? Don't know what 'Yn Saesneg' could be though. And shouldn't the Welsh for Barmouth Bridge be 'Pont Abermaw', since there's nothing before the word Pont to mutate it and the Welsh for Barmouth is Abermaw (mouth of the river Maw).
Sorry, might have been talking nonsense there because I can't actually speak or read Welsh, I've tried a few lessons and haven't really got beyond 'dim sharad Cymraeg' but I've seen enough road signs etc. to know things like Barmouth is Abermaw.
I think we need to get a line painted across the end of the level part of the platform, with a warning sign that the public should not proceed beyond that point onto the slope down towards the track.
Why not? It's a ramp, it's part of the platform and it can be walked on safely. Just so long as they don't get all the way to the bottom and put their feet on the ballast. You make an intersting choice of wording though, where there are such signs it often says: "Passengers must not pass this point of cross the line". Some pepole on the platform may not be passengers, so the wording of the sign does not apply to them even though it probably should (although not in the case of one such sign at Aberystwyth which is daft, as there is recently refurbished perfectly serviceable platform beyond the sign).
