Well currently Epsom Downs doesn't have Sunday services or for that matter a
ticket office (the station building is now a nursery) but the other stations
do and the point does apply to evenings. In the old days the solution was
obvious - buy a permit to travel and sort it out on the train or the
destination.

But a permit to travel only covers the user from the starting station to
a point at which they can pay for a ticket.

In the case that you cite, the passenger will already be covered for the
first part of their journey by their season ticket - the OEP is needed
to cover the later part of their journey, when travelling outside their
zones.

What I'm saying is that the situation from 2/1/2010 is no worse than it
is at present - the journey will have to be interrupted at some point in
order to either buy an extension ticket or collect an OEP if neither are
available at the start of the journey.
