I think it's a damaged culvert under the Aylesbury end.

I think it's a damaged culvert under the Aylesbury end.

Is this anything to do with the deviation being built for the HS2 bridge?
That is at the Aylesbury end.

 

[LowLevel]

Don't think so. If I remember rightly it's directly under the points on the branch or something along those lines.

Thanks for the info.

or something along those lines

Bonus point for the pun.

Much confusion at High Wycombe on Friday when the "Aylesbury" service was terminated short on plat 2 (down line) instead of the bay. Cue many announcements and passengers (heading for stations to Marylebone) running up and down between platforms looking worried. The bay was empty, maybe it was OOU.

Is the P Risborough/Aylesbury line actually being deviated for HS2? Presumably over the new (rusty) bridge which has been on site for some time.

The rusty bridge is weathered steel

Known as Corten steel, I believe. "Supposed" to look rusty as a feature and not indicative of poor build. The 'rust' actually protects the surface below.

That does look like significant work to rectify. The defect looks well inside the culvert. I assume it was a routine inspection that picked this up as can't imagine that something so far inside would have been found any other way, unless there were slippage visible above on the surface.
