Does anyone know why this gateline was finally removed?


As an interchange gateline, it was presumably thought unnecessary following
PAYG extension (although it may just be coincidence). *It was pretty much
unique, as there are plenty of other stations where you can get into the
underground directly from other NR services, and the same requirement was
not applied to Central, DLR and LO at Stratford.


I think Paul Corfield has explained in the past that there was originally
thought to be too great a revenue risk at Stratford - that view must have
been challenged within LU I guess - and of course the maximum cash fare now
covers the costs if you touch out elsewhere on the Jubilee without touching
in.


Not quite - there was simply a policy decision to gate off the Jubilee
Line as far as possible. The only place it could really be done was
Stratford. *It wasn't exactly feasible to put gates on all the
connecting corridors between lines at Waterloo or London Bridge!


West Ham might have been do-able though, in the bridge passageway - it
might have also had to take in the NLL platforms (as well) though.


It was first switched off last November or December sometime though, there
were posts here about it if you search back.


I actually think this is all to do with Oyster on National Rail. *The
need to have so many Oyster OSIs in order to calculate the proper
through fare on the correct tariff and time band is probably the thing
that caused the concept of an interchange gateline to be abandoned. The
additional intermediate validation meant you could have two exits in a
row or two entries in a row. *Oyster PAYG works on "in then out" to
determine correct charging. *My guess is that a patch was possible when
PAYG was TfL only but once you expanded it wider then the patch became
unworkable and a system redesign for one location was not financially
justifiable. * The timing of going to "open mode" late last year is
almost certainly related to the downloading of revised software for PAYG
on National Rail.

The above is my speculation - I have no inside information.


I was in Stratford last September and saw something quite bizarre - a
couple of the Jubbly gates (in each direction) had standalone
validators fitted next to them and these featured pink (interchange)
pads, so it almost seemed as if some pax were going to be expected to
validate twice to get through the gates. This kinda blew my mind! I
did take a couple of very bad photos, but the Jubilee was closed that
weekend so I never saw if this arrangement was ever actually used. I'd
intended to post here about it, but things happened and I wasn't on
utl for a while thereafter, so I never got round to it. I'll try and
find said photos (which is something I'm sure I've said beforehand
though!). When I was next passing through Stratford in December (I
think), I took a look and found the gates locked open (with Oyster
pads inactive/ turned off), and the four or so standalone readers
active with yellow pads - this remained the situation a week or so
ago.

I'm wondering if the extra standalone validators were some far out
kludge that someone had devised to supposedly sort out some
horrifically complicated issue connected with the PAYG expansion - if
so, thankfully it got vetoed at some point (because it would have been
too confusing for words!). But these extra standalone readers were
definitely new installations as of sometime late summer '09, so
whatever it was had got far enough along the line to leave the drawing
board and assume a physical manifestation in the real world.
