Oyster National Rail charges

[elucidate]

Hi all,

I have a Railcard discount applied to my Oyster card.

Today I used my Oyster card to conduct a return journey from Southbury to Manor Park via London Liverpool Street. The outward journey was during peak hours and the return was off-peak.

The Oyster card charges I should have incurred are mentioned on this link, where different routes are given:
http://www.tfl.gov.uk/tfl/tickets/f...nor+Park+[National+Rail]&ft=National+Railcard

For the outward journey, I touched in at SBU, touched at LST, and finished by touching out at MNP. I was correctly charged £4.60, as mentioned in the "Route 1" section of the page.

For the return journey, I touched in at MNP, and then touched out at SBU at the end of the journey. I did not touch my Oyster at LST because the ticket barriers were open. For the return, I found that I was charged only 90p.

These are my questions:
1) For the return, why was I charged only 90p?
2) The link mentions a 'single fare' of £6.20 peak and £2.20 off-peak between SBU and MNP. As it is not possible to travel between the two stations directly, in what circumstance would I have been charged at these prices?
3) With regards to Routes 2 and 3, at what points should a traveller touch their Oyster card on a reader?

Thanks.

When was your outward journey? Was it in the afternoon peak? If so, the 90p was to bring it to the Off-Peak cap for Zones 1-6 which is £5.60.

The £6.20 fare is a Zones 1-5 National Rail/LU through fare. I am not sure when it would be charged as I can't see a sensible route which would involve such an itinerary.

I don't usually refer directly to an answer on my site, but as you've posted the exact same text, including the typo where the fare charged was £4.70 (not £4.60), I'm going to. The answers are at the bottom of this page: http://www.oyster-rail.org.uk/fares-guide/
