Oyster PAYG on National Rail; Out of Station Interchange

http://www.oyster-rail.org.uk/ - I've just discovered this site and on this page

http://www.oyster-rail.org.uk/out-of-station-interchange-osi/ it lists the "out of station interchanges  - ie like Aldgate - Fenchurch Street where your PAYG journey does not count as being broken, even though you have gone through the street,. just as if you had changed trains within a station.

A useful one is Leytonstone <--> Leytonstone High Road for we bikes-on train afficionados.


I don't know if it's authoritative - there seems to be discussion about where it has allegedly gone wrong
