During my trip out on the Chiltern Line in the week, I took the opportunity to take some pictures at Princes Risborough and Bicester North to compare the track and platform layouts now the work has been completed compared with the situation before.

Here's the results:

PRINCES RISBOROUGH (before on the left, after on the right)


























BICESTER NORTH (before on the left, after on the right)

You might want to label before & after? To somepne who knows those areas very well, not even I can easily work out which are the new ones @ BCS. by elination, its doable (the unfinished platform being a give-away!)

But for those who don't know the line, the PRR (Princes Risborough) photos could be difficult

Shame it isn't 4 tracks through both, tbh. It may not be needed for the timetable, but it would help in disruption.

As would spending ^millions on many other projects of course, not just those you mention. Four tracking through the tunnels into MYB (London (Marylebone)) would be even better! But it aint going to happen, any of those!

But I would assume retaining 2 fast tracks through both stations above would have cost relatively little (or less, as no platform movement). At least keeping the space for them so they can be added later at little cost.

As I've said, I'm a little surprised how they did Bicester, though an Up Bay platform could easily be installed at any time using the grassy area visible in the first pictures of Bicester above.  That would add a certain amount of flexibility, although the number of trains terminating there will reduce dramatically once Evergreen 3 is complete and the majority of trains turn left to Oxford before Bicester North.

At ^1million per point, it was a lot cheaper to do what they did. Funds were limited. They did what they did to get best performance for the funds available.

More may follow in their next franchise bid, but that's it after Oxford

Thanks very much for those photos, IndustryInsider: in particular, for taking the 'after' pictures from exactly the same position as the 'before' pictures.

It's all very useful to those of us who aren't familiar with the line!  Smiley

William Huskisson MP (Member of Parliament) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: stop, look, listen.

"Level crossings are safe, unless they are used in an unsafe manner."  Discuss.

At ^1million per point

[Insert a joke here linking money growing on trees to "Evergreen" 3.]

Seriously worried about the effect of OXF» (Oxford - next trains) services. Assuming extensions of paths only and no new rolling stock, I think a 3 or 4 coach 168 will be full by Water Eaton (definitely by Bicester). Thus commuters from Thame may struggle to get a seat (although it will no longer be Oxford's new station!).

Trains will leave London full and arrive at High W where tired commuters may face scrum conditions to get a seat (unless lots of people get off). I think the OXF to High W is expected to be a sizeable flow.

Hmmm - I'm worried that Chiltern is beginning to suffer due to its own success. Cry

Lots of people *will* get off in the evening, so I don't forecast that being a problem.

However, I do agree with your commrnts on the AM peak, in that pax from HWY will outnumber those from OXF» (Oxford - next trains) getting off, so few if any seats for HWY pax.

I disagree however, with your OXF-HWY forecast - I think it'll be not very many. They must be driving right now-no other ublic transport company sees a flow there....so, even if you're right, Chiltern will need to get them out of their cars, and parking isn't exactly a problem currently in Wycombe.

But the flow, if there is one, is *into* OXF, I reckon. There is more employment in Oxford than Wycombe

Are there some more loco hauled rakes being introduced over time?

Yeah, sorry I meant HW to OXF» (Oxford - next trains) flow. Even if the flows are next to nothing, there is risk of OXF services turning into sardine specials.

Re rolling stock: I hope so! Plus they're getting plug doors to help with dwell times!

I believe the idea is that the hourly mainline fast services will be LHCS (Locomotive Hauled Coaching Stock) all day, once they need to diagram more 168s on Oxford services.

As they are fare setters from Water Eaton -  MYB (London (Marylebone)), I think they can adjust them to achieve the loadings they want....
