There's an actual description of what happenned he
http://www.raib.gov.uk/publications/...wn_station.cfm

It implies the driver tried to go southbound when they were meant to
continue north to High Barnet.

Interesting that an incident which had no direct consequences should appear
so instantly on the RAIB website.

It led me to peruse the rules they publish about what they need to be
notified of, and how quickly (all nicely linked from the website). I
pondered long on what category this incident fell into (which apparently
required immediate notification).. I couldn't find any relevant category
(no derailment, no long-term blockage, no injuries, no expensive damage) ..
until I noticed that Category 1(9) (the last category requiring immediate
notification) reads:

========
1(9) Accidents or incidents which could have lead to deaths or serious
injuries or 2m euros worth of damage to trains, infrastructure or
environment, but did not do so. If in doubt notify.

========

I find it difficult to think of any incident which wouldn't fall into such a
category - pretty much rendering all the other categories irrelevant. I
wonder how it's supposed to be interpreted in practice..

What might have happened here then - have the BBC described the
incident
correctly, or were the brakes applied by the operation of the

Surely the Camden town junctions don't allow trains in opposite
directions
to meet, thats the whole point of all the branch tunnels...

The Service (Line) Controller made a Code Red to the trains in the
area.

It was a re-numbering of trains that didn't quite go to plan.

Presumably a 'Code Red' is an emergency stop. Does a 'renumbering'
include
trains reversing short of original destination or something? Was this
as
scary as the BBC suggest then, or was it protected by the signalling
system?

Paul


Sorry I didn't explain it properly. A Code Red is for all trains to
stop immediatly.
The signalling system did not prevent this from happening.
The re-numbering involved the train still heading in the same
direction, but to a different destination, as part of a re-numbering
with another train (that also had its number and destination changed)


From RAIB web site:

"At approx 17:35 hrs a northbound Northern Line train was incorrectly
signalled into the High Barnet platform at Camden Town when it was scheduled
to go to Edgware. To minimise passenger delay the following High Barnet
train was signalled into the Edgware platform, and arrangements were made to
exchange passengers and crews between the two trains. When the train in the
High Barnet platform was ready to depart it set off in a southerly direction
for a short distance; the driver saw the lights of the next northbound
train, which was standing at a signal, and stopped the train."

A nice clear explanation for the layman

This was in the evening rush hour so it was potentially disastrous.

One wonders why the motorman didn't notice there was no signal at that
end of the platform.

You're right, I didn't check the day.

You'd think he might have noticed something like that. What did he
do , see there was no signal at all and just thought "ooh , that must
mean green"? What a dick. I hope he's fired just like any bus or truck
driver would be if they drove the wrong way down a main road though
I'm sure Bob Crowe will crawl out from under his rock at some point
and try and blame LU or Metronet for it.

Um, no signal *does* mean green. Unlit signal - not the same thing -
means red.

Having said that, I can't offhand think of any LU station that doesn't
have a starting signal at the end of the platform.
