I've been asked about a signal allegedly at the south/west end of the
eastbound platform at Gunnersbury (that is, at the Richmond end of the
platform used by trains coming *from* Richmond). I'm not aware of any
such signal - there are no routes from the east into that platform - and
won't have a chance to visit in the near future. Does anyone know
anything or can describe it to me?

There's an elevated Limit of Shunt signal at the Richmond end of the
Up platform (no. GB507). As you say, there are no routes reading up to
it. It's fitted with a trainstop and it's there to prevent trains
setting back wrong road to Richmond without authority.

I go through there quite often but don't recall such a signal. Next time I
go I'll try to remember to look for it.

There's also this page:
http://www.trainweb.org/districtdave...nnersbury.html

which explains more about the reversing move back to Richmond, from an LU
point of view, although it does not mention the 'LOS'.

Including that the offending move (as done on at least two previous
occasions) being prevented is a train returning to Richmond "wrong
line" in error rather than proceeding past the crossover at the London
end of the station and using that crossover to return to Richmond on
the Down Line.

Thanks to both of you.

Do either of you know what's on the plate? The PDF seems to show three
rows of text.

So is it exactly the sort of set up the RAIB revealed is not 'cost
effective' following the incident at Camden Town?

I'm not certain, but I think it's "GB507" over "LOS" over a right-hand
arrow.

The circumstances were slightly different. IIRC Camden Town involved a
one-off incident of a driver setting off "wrong line" after forgetting
which way he and the train were facing while at Gunnersbury there was
a (repeated?) misunderstanding of an instruction from a remote
signaller concerning a train being sent back by the same route (but
not wrong line). I haven't got the details of the Camden Town incident
to hand but one thing possibly missed by the driver was that before he
set off he failed to check the platform starter; had he done so then
its absence should have indicated something was wrong. For practical
purposes he seems to have compounded the event by doing a one-man
"ding-ding and away".
