Overground to Underground interchange at Euston

Ahhh...I think what he means is you shouldnt have touched in at Euston Underground. Ive no clue what an interchange reader is, but pesumably in this case it validated your oyster for the next leg of your journey by underground. When you then touched in at the underground station, it thought you had already 'started' your journey, not finished it, but then started a new one. In the systems eyes then, you didnt touch out from the previous journey, hence the penalty fare.

Possible?

Well, it is oyster after all!

Ive noticed myself they seem to sometimes refer to things on the help line that are...obscure/unheard of.

Vaulted the barriers, obviously....

The only thing I can think of is to tell the staff at the gates. However, its useful to know that such a pecularity exists at this station. It would be a great reference if all these oddities could be listed in one place so as to forwarn people?

ChrisM you did the right thing at Euston as that's an interchange I've made fairly recently over the last two weeks, without problem, but I will check to be sure when I get chance.
I assume you touched in ok at the start of the journey and completed the journey in good time.
Also confused as to why you were charged £3.40...

Did you use the readers attached to the barriers (as opposed to a stand alone by a manual gate)? Or is there a chance of a double touch?

How vexating!

Yep, I touched in at South Hampstead and had just under 10 minutes to wait for the next train, which arrived at Euston on time. It was also less than two hours between touching in a Sotuh Hampstead and touching out at North Greenwich.


Some (but not all) of my journeys on Saturday are now online.
At Ruislip, I entered the system and my card was debited £4. On touching out at Northwick Park I was refunded £3.40, meaning that the journey cost me 60p. At this point I reached my PAYG cap for the day.
My next journey was from Kenton to South Hampstead. On entry at Kenton, £3.40 was deducted from my card, and refunded in its entirity when I touched out at South Hampstead. When I touched back in again at South Hampstead, £3.40 was again deducted. This is where the online journey history currently ends.


I used a reader attached to the barriers.
Thinking about it, it is possible I also touched on a stand alone reader on the platforms but I don't know for certain. I didn't know that there were barriers at the platform end so its possible I'd have touched on the first Oyster reader I saw. I'm sure I've done this sort of thing somewhere else before without it charging me for a double exit at the same station.

As we arrived on platform 9, there was a London Midland service (to Milton Keynes iirc) on the adjacent platform 8. Had I wanted this service, it would be very useful to just be able to tap out on the platform and get straight on the train, rather than walk to the barrier, touch out, turn round, get out my NR ticket and pass through the gates again.

I don't remember whether there were such readers or not though.
