Wonder if any of the resident Oyster gurus can assist me? I regularly
make the journey from Honor Oak Park to Watford Junction and have
until recently not paid much attention to the fare (using unregistered
PAYG, so no journey history). Lately I've become curious as to the

that it doesn't take three hours". Used to take NR from Honor Oak to

correct in assuming this is an expensive way of doing it? Recent
experiment has been Overground to Whitechapel, pink validator, H&C to

Suggest you try the TFL journey planner. This shows a variety of routes (not
yours) with journey times around 65-70 min. In each case the entire journey
is on Oyster with a total single fare (see their fare finder
http://www.tfl.gov.uk/tfl/tickets/fa...t/default.aspx )
of £4.00 peak or £2.30 off-peak. However, all the routes go via Zone 1 and
it is not clear whether or not these Oyster fares include that.

On reflection, if you don't mind a 2 hour journey you can avoid Zone 1
completely and pay £2.30 with Oyster:
Honor Oak Park Rail Station
Take Overground towards Highbury & Islington Rail Station
Canada Water Underground Station
Take the Jubilee Line towards Stratford Underground Station
Stratford Rail Station
Take Overground towards Clapham Junction Rail Station
Willesden Junction Rail Station
Take Overground towards Watford Junction Rail Station
Watford Junction Rail Station

"Help and Contact", "Make a Complaint", "Oyster", "Fares/Refunds" and
fill in the form. I can't remember experience at mailto://oysterenquiri

Give it a week to see if they automatically give you a refund to be
picked up at your home station. I think your chance of making an
effective complaint at a ticket office is low.

Appreciate the replies. In the Honor Oak via Whitechapel route, it
probably was £2.30 rather than £2.50. Only reason I initially thought
of that route was knowing where the pink validators were from
previously using the station (en route to see Iron Maiden, of all
things!). I did think about the "via Stratford" option to avoid zone
1, but having previously used the Overground up to H&I and then to
Willesden Jnct, it simply took too long to be practical. The other
thought I had was going the other way via Clapham, but again, there's
a NR Oveground link (unless meeting the Southern direct to Watford)
and I wasn't sure what the touching in/out rules were at Clapham.
Couldn't see any obvious pink validators last time I was there and
it's not a station I enjoy using if I can help it, so not really
inclined to hunt them down. The "via Whitechapel" route is only
slightly longer time wise than NR to London Bridge, so that's the
route I'm adopting for now. I know an OSI applies between Euston
Square and Euston, so was just curious as to how that fitted in with
the final fare. If it is indeed possible to get a route history from
an unregistered PAYG, I shall give that a whirl. I've certainly been
charged the £7.70 fare in the past, so it's quite nice to know it can
be done for a third of that with very little time penalty!

Hello Phil,

The OSI is indeed the reason you paid £2.50 for your journey.

The charging logic (assuming no cap applies during the journey) is as
follows:

Honor Oak Park entry: maximum entry fare deducted

Euston Square exit: difference between entry fare and single fare
refunded. So when you exited Euston Square, you had paid the Off-Peak
single fare = £2.50

Euston NR entry within OSI time limit: the journey from Honor Oak
Park is 'reopened', the difference between the maximum fare and the
£2.50 paid so far is deducted from the balance. The card chip retains
the £2.50 fare paid so far AND the maximum fare paid so far.

Watford Junction exit: The card reports Honor Oak Park entry (with
original entry time) to the gate / reader. The OSI exit and entry
stations are NOT considered at this point. The single fare is looked
up for Honor Oak Park to Watford Junction. Since none of the OSIs
which trigger one of the alternative fares was used, the default fare
applies: £2.30. However, the card also reports that the journey was
already 'completed' before being reopened at the £2.50 fare. The
difference between the maximum fare and the £2.50 fare is refunded to
the card balance.

Finally makes sense, thanks! I guess the key moral of the story there
is "always tap in at Euston within the OSI limit". Better to wait on
the platform and save a fiver than stand up in the concourse!
