As I've suggested before it isn't just the gating question - the main issue
with PAYG on a large network with maximum peak single fares priced
approaching £50, is what amount does a prepay user need on his card, and
what initial deduction does the system make, comparable with TfL's £4.00
'entry charge'?

All those who think joint ITSO/Oyster prepay can be simply 'switched on' on
mainline TOCs please explain...

For making a journey where you properly touch-in and touch-out, the
answer is simple. Use one of the combined Barclaycard/Oyster cards where
the traveller has a significant credit limit via the Barclaycard
element, which can be invoked when they touch out.

For unresolved journeys, there's a much bigger problem, even for people
with hundreds of pounds of cash on an Oyster. If someone touches-in in
London, do we now have to assume they failed to touch-out in Glasgow?
