Gerrards Cross - London Stations Route questiob

[oversteer]

Am I right in thinking a Gerrards Cross - London season ticket (London Stations any permitted) will cover me on Chiltern's very infrequent service from Paddington to Gerrards cross?

If so, would it also cover a trip with FGW to Greenford, with the intention of using LUL to South Ruislip and on to Gerrards Cross with Chiltern?

I assume the 'direct' requirement of the Routeing Guide precludes this, but it would be interesting to know.

OK to Paddington, but not Greenford

Yes.

I believe so, as I remember there being interavailability between LU and NR over that section of the Central Line. However I cannot find the exact documentation so will need confirmation from someone who can.

I assume the 'direct' requirement of the Routeing Guide precludes this, but it would be interesting to know.

It doesn't need to be direct trains as it is a mapped route.

It doesn't need to be direct trains as it is a mapped route.

Gerrard's Cross has London Group as an associated Routeing Point, therefore unless the Central Line is interavailable and the route via Greenford is no more than 3 miles longer (I guess that it's less than 3 miles longer) then only the direct route into Marylebone is permitted.

If the origin and destination have a common routeing point, the permitted route is direct via the shortest distance from the origin to the destination over which a regular scheduled passenger train service operates. No doubling back (passing through the same station twice on a single journey) is allowed which may require customers to change trains short of the routeing point, unless an easement allows a longer alternative route.

Yes I made a complete hash of it this time it seems. I just saw that Greenford was an associated RP and stopped there.

Anyway mileage is hard to decide as NRT does not contain information for the section between South Ruislip and Greenford.

Gerrards Cross - Marylebone: 18.75 miles

Gerrards Cross - South Ruislip: 7.25 miles
South Ruislip - Greenford: ???
Greenford - Paddington: 9.25 miles

So South Ruislip - Greenford is allowed a maximum of 5.25 miles.

2.51 miles according to Google Maps...

Google Maps isn't the decider, though, the timetable is.

Now the timetable should say it's fine.

Which timetable though - as bb21 says, it's not in the NRT. Given that it's a straight line, I'd be surprised if it were 'officially' 2.74 miles longer than it appears on the map.

Railmiles says 2 miles 42 chains, which is about 2.5 miles. I don't think it will be miles out. However as we all know, none of these are definitive sources of information.

For what it's worth, NFM99 Section L (no longer current) only had NR/LU interavailability between South and West Ruislip - no mention of Greenford.

And NR OJP comes up with a 'multiple tickets required' warning if you put in a 'via Greenford'.

What about using Oyster for the Greenford to WR/SR bit, would my Chiltern ticket allow me as far as Greenford?

But the Chiltern trains do not stop at Greenford so I do not see how the ticket would be valid

It's quite close. The info we get at Chiltern is that Marylebone is 27 miles and 62 chains from High Wycombe, and Paddington is 25 miles and 60 chains.
Using that as a benchmark, Paddington is 2 miles and 2 chains closer to all the stations beyond South Ruislip than Marylebone is.

The 40 chain discrepancy is easily explained. It could be one of many things, ie whether the distance was measured on the up via one system and via the down on the other. They could be measured to different signals. Again, looking at the information we were issued with, Gerrards Cross (19 miles 03 chains from Marylebone) is measured to the ground position signal in the turnback sidings at Gerrards Cross. This is easily half a mile from the signal on the end of the up platform.

Thanks. I think in that case the ticket would not be valid unless on the direct train.
