The Northern ones that I'm familiar with have the 'green halo' (or orange/red if its failed) that guards often look out for but I can accept that it isn't especially conspicuous.There is a pictogram that has been used for the last 60 years or so…
It shouldn’t exactly require much thought to realise that a sign pointing to the ticket machine(s) is a good idea - particularly where you haven’t walked right past it on entering the station. Having signs that show you from a distance whether it is actually working is probably asking too much!
I always thought that having the delivery slot marked "Tickets" was a bit of a clue that the machines don't sell chocolate but again I suppose that it could be more visible.
(Attached photo shows a machine at a Hope Valley station with the halo and delivery slot visible.)
