This may possibly be related to the original observed vanishing act - though it seems a bit unlikely for a direct train to Paddington. However, for anyone wanting to book to Marylebone changing at Oxford to a Chiltern service, that was impossible yesterday and is still giving trouble today.
There is a thread on railforums about pathologically miswritten easement, which was:
00948 (Circuitous Route) Journeys from or via Princes Risborough to or via London stations are not valid via Oxford. this circuitous route easement applies in both directions.
The "via" stations can come in any order so this bans any use of Chiltern trains from Oxford unless you start from there. It's not clear what circuitous route is was trying to stop - but whatever it was, it was wrong. The code on the data feed went further, specifying Oxford as via or to/from - and all journey planners should have obeyed that! So that was even wronger: barring direct trains to
MYB▸ too. (Though arguably the
OJP▸ should always allow those and not even look at easements.)
Presumably that easements file was loaded yesterday (or earlier for activation yesterday), and there was another one today in which that easement has disappeared. But loading the file takes time, and I think is done overnight, probably with the OJP offline.
As of tonight, the
NRE‡ OJP still can't find a valid ticket using Chiltern. Even when told to avoid Paddington, it routes to there and on to MYB. It does not offer through tickets either, though there is a one-way fare, that is unlikely to be meaningful, as it also complains:
We are sorry, we are not able to find any fares that match your journey details. There are some possible reasons below. Please try again.
You specified a 'via' station, but also asked for the cheapest fares. The cheapest tickets may not be available on the route you requested. Try again, without the via station.
There are no trains running when you want to go. Try again, travelling at a different time.
The
GWR▸ OJP finds a super off-peak at £62.20, which I think includes the Tube
PAD» >MYB - but shows a routeing direct
OXF» >MYB! After a few seconds it removes the list of trains and shows "Sorry, there was a technical error [
whatever that means] while searching for your journey. Please try again later".
I presume these are transient issues due to the new file not being loaded yet. The correct super off-peak fare, as rogerw says, is £56.20 for allowed return times, as it is "any permitted route" and both lines are in the routeing guide from Oxford (the routeing point for Evesham) to London Terminals.
Anyone for a bit of simplification?
