Post by Alan J. FlavellQjump shows a saver return Manchester Stations to Luton-A.P, route NOT
LONDON for 44.80, but seems to have a hard time finding journeys.
Well, this is turning into quite a little puzzle, if any fans of the
routeing guide are willing to bear with me. Sure, the original
posting on which this problem was based is long since expired, and
I've no practical interest in travelling the route myself, but somehow
the puzzle lodged in my mind for its own sake, and, now that Clive's
CORE is back online, I'm even more baffled than before.
Here's the puzzle. If we look for fares from Manchester (let's say
Piccadilly for the sake of definiteness) to Luton Airport, there's a
saver fare "NOT LONDON" at £44.80. The question is, what routes are
valid for this fare? - (and why?)
Direct trains - none
Shortest route - CORE says it's via Stoke on Trent and Derby and
Lufbra and Leicester... 166miles62ch.
Qjump finds no journeys by this route. HAFAS, given a bit of help by
setting a couple of via points, seems as though it might have found
some, but there seems to be inadequate detail to be sure that it
really complies with the shortest route according to CORE - I suppose
some local knowledge is called for.
As for the mapped routes, the routeing points for Luton Airport Pkwy
are Bedford, Watford Junc and West Hampstead.
The quoted SVR NOT LONDON fare to Luton Airport is 44.80, but the
corresponding fares to the routeing points are ALL higher. The
instructions in the routeing guide say that if this happens:
In exceptional circumstances, due to local fares policies, a direct
comparison may not be possible. If this is the case and the origin
station or destination station has a lower fare of the type selected
than all its routeing points, the Standard Single (Day or Open)
fares should be used for comparison purposes.
OK, so I compare the standard single fares instead, as instructed.
To Luton Airport NOT LONDON: £89
To Bedford NOT LONDON: 92
Note - to Bedford ROUTE CHESTERFIELD: £35 (!)
To Watford Junction NOT LONDON: £91
To West Hampstead: the only fare is ANY PERMITTED (£92).
So, again, the fare to the destination (£89) is less than ANY of
the comparable fares to the three RPs.
Does that mean, then, that there are no mapped routes available?
Or are we supposed to take the ROUTE CHESTERFIELD fare into account
in some way? There are no instructions about that, are there?
Or, perhaps there's an Easement?

I don't see anything relevant there.
So much for the routeing guide theory. Now for the Qjump practice.
[In general here's what I'm doing. From the main query page I set up
a return-journey query, from Manchester Picc. to Luton Airport, and
UN-check the fastest trains option. VIA point either not set, or set
as noted below.
Then I proceed with the query, and in general it comes up with a
selection of journeys for which no fares are available. Then I
take the "more fares available on this day" and I find amongst them,
the SVR "not london" fare cited above. Then I ask what journeys are
available at that fare.]
If I give it no assistance with a Via point, then it comes up with
only *one* outward journey, leaving at 02:18 for Sheffield, with a 2hr
wait there before continuing with MML via Wellingborough.
For the return journey, however, it finds three journey opportunities.
- One involves changing at Bedford and Sheffield
- One connects at Luton into a train directly to Manchester (via
Leicester and Stockport, apparently)
- One is routed St.Albans (walk) Abbey, Watford Junction, Manchester.
If I try to help Qjump out by giving Sheffield as a via point, it
finds nothing additional.
However, if I try to help it out by giving Watford Junction as a via
point, it comes up with several journey opportunities, in -both-
directions, which follow that route via W.J and St.Albans, and vice
versa, which it hadn't offered before. Recap: it claims that these
are available for the cited £44.80 NOT LONDON fare.
So now I have a list of 6-7 journey opportunities each way, by three
different routes, which Qjump say are available for this £44.80 SVR
"not london" fare, but for which there appears to be no basis under
any of the headings in the routeing guide ?!?
And NONE of them follow the route which CORE reports as the shortest.
(Yes, I know that CORE makes no claim to be authoritative, fair do's.)
Funny farm time?
