TfL's offer to the National Rail (NR) Train Operating Companies (TOCs) to
fund the £20 million cost of installing equipment to allow Oyster
Pay-as-you-go (PAYG, a.k.a. Pre-Pay) isn't open ended, and the deadline -
the 31st of January - is fast approaching. It would appear the Mayor is keen
to bounce the TOCs into signing up to the deal.

See this TfL press release:
http://www.tfl.gov.uk/tfl/press-cent....asp?prID=1037

The full release on the Mayor's site is a tad more revealing and also
includes a wonderfully inaccurate statistic about gate throughput.

I can see how they came up with the numbers, but it certainly doesn't
apply to the newest gates (as at KXSP, Marylebone NR etc.)

You can? Please tell me.

Hmm, on further review...

I did wonder if I'd missed something.

I know what the numbers are as I used to test the gates, know the design
spec and used to calculate all the gate quantities for LU stations. I
can tell you that 15 people per minute for magnetic tickets is utterly
wrong

That is too low. It doesn't take 4s to activate a gate.

25ppm is the planning capacity per walkway.

while 40 for Oyster only is pushing the upper limit of what is
possible given the western sense of personal space.

I think that's based on how long it takes to read the card and return
to a state able to accept the next card being 1.5s - I don't know if
this is accurate, but it's plausible.

I've seen (and taken part in) a demonstration at Cubic's UK offices
where we got just under 40 people a minute through a gate. The paddles
never moved as the ticket transport / target was permanently activated
and thus no instruction to close was given.
