Following on from this thread - https://www.railforums.co.uk/threads/trivia-signals-that-never-show-green.180040/
Are there any signals which have not changed aspect for years? I seem to recall that when a line is lifted the junction is still signalled as it's easier to show a signal at danger than resignal the area. So, what's the longest - and do the bulbs need changing? Are the other aspects ever tested even though they will never be used again?
