They're not always popular in London. Maintaining and improving a complex computer railway that's well over a century old in parts and has never been updated properly on an unrealistically tiny starvation budget isn't the easiest of jobs.
But they do seem to make an effort to be practical and engineering-positive in a way that's quite rare in the UK.

Ex: Hazard icons, speed limit signs, etc.
I believe there is a genuine beauty when you're in the network and have the lovely design on shorter sections(Olympia branch on Piccadilly/District springs to mind), or the simplistic single line vertical maps on the entrance to individual lines.
Having helped tourists navigate the hotspots it becomes clear that the people most in need of a map often aren't helped by the current complexity in parts. Renaming stations might be a nice idea too. Imagine hearing the Covent Garden message if you're a foreign tourist, or British but new to the word alight ;)
