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
http://www.metroland.org.uk/cheshamflyer/


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).

Guy Gorton


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.

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

Yes. And, oddly enough, it's still the datum point for the whole LU
network.

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.

How long did the trains stop while the locos were swapped? Was it really
as little as four minutes?

It would probably take at least 20 today, if it were allowed at all. Can
you imagine them allowing the crew to be working on live fourth rail
tracks, with steam and dripping water all around?

The event I attended was well advertised and there were a lot of
railway buffs watching so it took quite a long time. It may even
have been a Special from Baker Street but I cannot remember.

In article , writes
Yes, it still has trip cocks. The new signalling hasn't got that far. So,
unlikely to be a SPaD.

Presumably Chiltern won't be paying for the met line train control system
to be fitted to their DMUs so I guess TfL will have to fork out for that
when the time comes. I wonder if its worth it given the trains on that
section arn't exactly frequent.

If I remember correctly, that section will have "overlay": the new
system will drive the coloured lights to show the correct colours
corresponding to the issued movement authorities.

Richmond and Wimbledon, on the other hand, will have "underlay": the
signal aspects are fed back to the control centre which generates
movement authorities to correspond.

(I may have the names the wrong way round, but the concepts are right.)

Never got further than Rickmansworth because of the damned restriction
they placed on the five-bob Twin Rovers. So I only saw the high-speed
loco changes.

What would HSE say about that process nowadays?

Was it not the most distant station between 1961 and 1994?

I went to a Steam on the Met not THAT long ago. They dropped a piece
of old carpet over the centre rail when they went between for
coupling. They had no need to go anywhere near the third rail.

Would a wet carpet provide effective insulation against 210V?

Unless I'm misreading http://www.davros.org/rail/culg/

Ongar to Bank: 37.77km - 0

37.77km from Chesham is just about Finchley Road

Of course, those as track kilometres, but Google Maps gives the direct
distances from the City of London as Chesham 42km, Ongar 31km.
