Sir, - Spectator's item about the sign on Tubwell Row reminded me about the one on Yarm railway station.

This was installed some time ago, gave the time and said "Welcome to Yarm Station". It now reads, and has for some time, "Sign under test"; and the real gem was that at one time it said "Ask station staff for information"

and, of course, Yarm station is merely an unstaffed halt. It makes me wonder what the purpose of this sign is.
