But diamond signs are provided on TCB lines. The only reason you don't often see them there is that nearly every signal has an SPT.No disagreement with the second part, but I'm not sure it makes any difference whether an SPT is provided or not (I can certainly think of numerous signals with a diamond and an SPT). I thought that the method of working was relevant as diamonds aren't provided on TCB lines (otherwise every signal on the WCML would have one, as you say).
For the avoidance of doubt, this discussion is about plain white diamond signs. Diamond signs bearing a letter L, T or X are a different matter - those ones are only fitted to signals with SPTs.
