I was talking to someone else who stated that a platform at Epping was
still vapourware; to make up for this, the group has a rather nice
RTL-class Routemaster, painted British racing green and bearing the
code RTL1256, which they intend to run between Epping LU and North
Weald for onward connections.

Good post.

However an RTL is an RTL - not as Routemaster. And presumably 'British
racing green' is London Transport buses country area livery?

I don't know a bloody thing about buses, so I will take your word for
it ;-)

Bus aficionados will really like it; it's in amazingly good condition
and looks excellent on the inside.

What's a single-aspect signal?

A signal with only one aspect.

Sigh. Okay. What *use* is a single-aspect signal?

Fixed distant, or fixed stop signal. Not what I'd expect to find doing
an inner home job, though ...

om...

I looked at the signalling diagram for the LW and LX sites and
it makes no mention of a west-facing single-aspect signal at Ongar;
only LX21, the two-aspect station starter, and an FRL, are shown.
Does anyone have any more information?


The signal approaching Ongar was a fixed yellow, designed to act as a
repeater for the red lamps at the end of the line. This arrangements was/is
not unique on LU - I think there is a fixed yellow approaching Chesham, and
also most tunnel sidings have sequences of them. Most are un-numbered,
however the one at Ongar was unique in that it's ident was "ONGAR".

I would guess it was installed as part of the post-Moorgate enhancements.
Most termini would have the last signal held at red until the train was
proved to have slowed, but presumably other arrangements were necessary at
Ongar because there weren't any approach signals. Obviously the yellow
isn't going to stop a fast-approaching train, but it would provide
protection at night if a driver couldn't see the landmarks where he had to
start braking for the terminus.


This signal had a trip thing that went down a certain time after the
train has passed the signal - it was away from the signal. If the train
was approaching too quickly the trip thing would of still been up and
set of the brakes.

Oh, of course.

Sounds like an approach-controlled trainstop, to prove the train is at
the proper low speed before allowing it access to the platform.

Agreed, or a trip thing as I like to call it.
