So I went to Vauxhall and checked out what you said.
Sure enough there was a revenue exercise there yesterday.
You ask what it is that they can see that the gates dont?

They are solely checking for people who travel through zone 1 without a
zone
1 ticket. This is marked on the ticket with the nice colour
triangles...easy
to spot without actually reading the ticket. If it was bought north of
the
river in a zone 3 to a zone 2 station it will have north colourings. It
will
still let you out in a zone 2 station allowing you to travel through zone
1.
RPI sees the north colour triangles, checks it is valid in Z1....hey
presto
if its only a £1 ticket....
Incidentally...they caught heaps.

So is the coding on a paper ticket not smart enough to establish that
a journey is made across zone 1. It seems pretty fundemental to me. If
you buy a zone 2 ticket at say Chalk Farm then travel to Vauxhall then
you must have crossed zone 1. The gates have only been around for
about 15 years, couldn't that check have been part of the programme or
am I missing something here. Do the gates only check the validity of
the date and that the exit zone matches the zone on the ticket.

I'm not going to go into detail about the coding practice (as I do know
exactly how it works) but I think people need to separate their thoughts
between how single tickets work and how season based tickets work.
There are different validities that apply and therefore different checks
performed by the gates.

Yes Kevin...thats about it. Remember its a private company that runs the
ticket system and it was a cast off from another place....

Would you care to tell me where it was cast off from as I worked on it
for years and years and I'm not aware it's a "cast off" from anywhere.

Oh and I was involved in the Prestige deal and I'd love to know what
difference contracting Transys to run the system makes? Do you imagine
that commercial policy has been ceded to the private sector as well?

If you're going to make statements then get your facts right.
