Indeed. Personally I think a simple statement of facts is what's needed, along the lines of "no direct trains between x and y on z date", rather than meaningless instructions.
is that not what the image in the first post basically says?Or just say "no trains to Kings Cross" then.
I've seen the "don't travel" message in Leeds, which can't be good, given that most services using Leeds won't be affected anyway.
No trains to KX, Do Not Travel, as any alternative route will be so unpleasant you’d wish you hadn’t.
