Hi all, Travelled the Welsh Marshes line on Friday and noticed there are a lot of semaphores - and mostly lower quadrant ones at that. Two questions that came to mind - is the line likely to be resignalled to colour-light before ECTS is introduced or are the semaphores safe for the next decade or so? Second, were lower quadrant signals ever popular outside the western region? Related, how comes the Western region never converted them to upper quadrant? Thanks.
