Can someone tell journeyplanner.org and all the other websites, apps,
etc etc, that if you want to go from Bowes Park to London Bridge, it's
a hell of a lot easier to change at Moorgate (down one tiny escalator
- about 20 seconds all in) than at Old Street (which takes about 3
minutes).

Everywhere recommends changing at Old Street, which I cannot
understand. Moorgate is so much easier.

Incidentally, when using PAYG, there's a yellow touchpad at the top of
the escalator. I have an annual so this doesn't concern me personally,
but merely out of curiosity, if a PAYG user did not touch that pad
with one's Oyster while making the transfer, could he or she be
charged for any non-starting or non-ending journeys? What with Bowes
Park being a National Rail PAYG fare-station rather than a TfL PAYG
fare-station.

(I know that TfL have just announced the getting rid of the £4
overcharge for when people forget to touch in or touch out - but if I
understand it correctly, this is only for when the system spots a
regular journey. And I guess it won't apply in the case of the NR PAYG
journeys either, though I haven't read confirmation of that, yet.)
