I noticed somthing interesting to me in the photo below.
The taxiway seems to have "3" Hold Short lines. What would be the reason for this?
Also, is this something that is only done at airports in Britain, or can you find taxiways like this in other parts of the world to? I've never noticed more than 1 Hold Short line at airports in the USA and Canada, but then again, I've probably never noticed anything in detail when looking out the window of an airliner that's taxing into postion because I'm always to darn excited!
I know there's different types of Hold Short lines (some are solid, some are solid with dash lines on one side or the other, some have multiple dash lines), for the purpose of identifying whether or not the runway past the hold Short line is ILS equiped, etc, or not and what category it is.
So, I'm going to venture a guess as to why this particular taxiway has 3 Hold Short lines. Could it be that pilots have to stop short of the line which indicates what landing system is currently in use?
