Idle curiosity, but does anyone know why there are a number of whistle boards along the Golden Valley line where there are two whistle signs on the same post.  An instruction to sound the whistle/horn twice?

Is it something to do with the high number of footpath crossings and curves reduce visability. The trains do seem to run slowly along that valley

There is nothing in Group Standards that I can see but GI//RT7033 on page 119 states that the sign should be at driver's eye level.  I wonder if a new eyesight level has been assessed (or just a scheduled renewal) and new signage has been added before the old signage is removed so that there can never be a gap in cover.
