How on earth can this happen?

Possibilities based on what I can see:

(1) Met train is heading for Chesham, the points are therefore set to
cross over, and the Chiltern train SPADed.

This seems the most likely to me. They are reporting that a set of
points was damaged, which would have happened when the Chiltern train
trailed through them.

The LU trainstop would have been at the stop signal, which is (Google
satellite map) close to the facing turnout which sent the Chiltern
train onto the wrong line.

Because the line was equipped with trainstops, not AWS, the driver
would not have had a warning at the distant signal, but he was
probably slowing down for the station.

Yes, considering that the Chiltern train should already have been slowing
for the C&L station, I'm surprised it got so far after hitting the
trainstop. I suppose it's lucky it wasn't derailed when it ran through the
Chesham-set points.

How on earth can this happen? Surely the chiltern driver knew what side of the
line he was on? And why didn't the tripcocks work or have they been removed
from that section of line now?

A lot of interesting history of the line at

I think that, thanks to the misleading Tube map, a lot of people wrongly
think that Amersham is the most distant LU destination, when it's actually
Chesham.

Certainly since the Met stopped going to Aylesbury. (Change loco from
electric to steam at Rickmansworth).

Which was well before the present majority were born !

I know it was probably only a threat, but how different it might be now
if the Chesham line had extended on to the LNWR.

The first 4 slides I ever took with the camera my father-in-law threw
at me 'cos he couldn't work it were of the last electric to steam
handover in 1961.
Extending to the LNWR would have been quite a geographical challenge
with both lines being in steep sided valleys. Lots of higher ground
between.

IIRC Ongar used to be the tube station most distant from central london and
that only closed in 94.
