What happens if there are two station, one of which has a machine
which is designed to take only cards

Then it is in full working order if it only accepts cards, although
it's not clear that such machines exist.

They do, although I've only seen them for definite at some big
terminals.

So what if the machine does take cash (not cards) but currently doesn't
give change ?

Not NR but Tramlink, today (only half the party had London Freedom
passes).

Phipps Bridge has two machines, one knackered (display looping between
'please wait' and unreadable hash) the other displayed 'change' at the
top and 'no change' when you got that far. When you asked for multiple
tickets to minimise the loss it seemed to say 'no tickets'.

So one of my party of Wandle path walkers pressed the stop's "advice"
button and got a code to use if we were gripped. I assume this is the
equivalent of the PTT, but the scheme would work at most unmanned NR
stations if set up the same way.
