I've just received an email telling me:

The RAIB is carrying out an investigation into an incident when a
road rail engineering machine ran away from Brentford to Romford on
4 November 2007.

Obviously it must have taken Crossrail, since going round the NLL would
involve climbing uphill.

So they mean Romwood, not Romford then?

Doesn't make sense to me. How can it run away when placed on the
track? Was it in gear and if so
didn't anyone notice any of the wheels turning? If it was purely by
gravity what sort of gradiant is on
that stretch of line that it moved off so fast someone couldnt' jump
into the cab?

"The operator of the machine jumped from it at Gidea Park"

Why didn't he put the brakes on?? Presumably they were working or it
wouldn't have been able to drive there
by road in the first place.

"The RAIB’s initial examination indicates that the maintenance
condition of the road rail machine did not contribute to the
incident."

Hmm, they always speak in code!

Did it have a working brake, but no-one put it on, not even the chap
inside who jumped off at Gidea Park? Or was the brake maintained OK, but
someone had disabled it in a non-maintenance kind of way?

I don' t know, but I have found out some more details. Services from
Liverpool St to Shenfield and beyond were using the Up & Down Main
lines, however the half-hourly Gidea Park terminators were using the
Electric [ie slow/local] lines, and turning round in GP middle
siding. The engineering possession extended from Gidea Park country
end to Shenfield. The trolley ran away (how I don't know) down the
steeply-graded Brentwood bank, out of the possession and on to the
operational railway. I have heard that a 315 had just gone into the
middle siding at Gidea Park when this trolley whizzed by 'wrong road'.

Then the person on board leapt off at GP platform, and the trolley
continued until it came to a stand by West Ham Utd's training ground,
towards Chadwell Heath station. So this had the potential to be a
serious incident, either for trackworkers (cf. Tebay) or for the
driver and pax of a down LST-Gidea Park service.

Typical cover-up. They don't want us to know the truth about the secret
tunnels they use to move the trains to and from the you-know-what!

Would someone be interested in reminding me why the RAIB and HSE or
whoever do parallel investigations?

IIRC, the RAIB investigations are into the cause of the incident, and ways
of avoiding a future recurrence, and not in bringing a prosecution of a
'guilty party'- indeed, I believe that evidence given to them cannot be used
in a prosecution. This followed HSE handling of certain cases, where certain
parties were advised by their lawyers not to volunteer evidence in case they
incriminated themselves.

what can happen with some machines, where the rail wheels are unpowered and
are driven by the rubbers, is that if the operator, whilst on-tracking the
machine does not put one rail axle all the way down before the other you can
end up with a situation where neither rail wheel is in contact with a rubber
tyre and the machine will start to run away.

if the machine controller is sensible he will chuckle to himself and wait 1
second for the operator to drop one end and stop the machine, but, if he is
a ****wit he will panic, hit the emergency stop button and leave the
operator rolling off down track in a machine with no way of stopping it.

i have only seen this myself on my machine controllers course where the
instructor did it on a short piece of track to show us what not to do but i
do know of worksites where it has happened for real.

since the report mentions a MEWP (mobile elevating working platform) it was
probably one of these http://www.readypower.co.uk/products/32, i have MC'd
these myself in worksites in this area, usually for balfour beatty OHL.

this method of driving a road rail vehicle (RRV) is called high rail, the
other 2 are low rail where the rubber road tyres sit on the rail and small
rail wheels are used only for guidance (ie land rovers) and independent
drive where separate (usually hydraulic) bogies are used, these are usually
used on tracked vehicles (ie dozers)
