The map I would find most useful is a 'turn up and go' map, showing all

to this, but this misses out some very useful national rail services and
includes some low-frequency tube branches. If the map were popular it
would give an incentive to companies to run more frequent or more
regular services. It should probably exclude anything Oyster isn't valid
on.

That mightn't be as easy as it might seem. For instance, Waterloo to
Wimbledon might be TUAG, Waterloo to Surbiton might be TUAG, but
Wimbledon to Surbiton might not be. (That's an imaginary example.)

And what happens with lines where there are longer gaps at peak
(sic)times, and shorter gaps during the day?

I agree this could be troublesome, but I suspect not in many places.
Colour coding, footnotes, and leaving some stations off, would solve most
of it.

They don't go on the map. I was using all day as shorthand for something
like 7am to 7pm.

Which could risk wiping a fair chunk of the map. OK, so few people might
miss Epsom Downs, and Wimbledon - Sutton is no good for turn up and go,
but Sutton - West Croydon is a fairly handy link between two towns which
people might feel it was a shame to drop off for the sake of 20 min
headways in the peak (it is still quicker than a 407 or probably an X26).
