Title: CrossCountry HST divided at Lawrence Hill. 31st October 2016
Post by: JayMac on October 31, 2016, 14:31:41
1S51, the 1224 Exeter St Davids - Dundee, a CrossCountry 2+7 HST set, has divided just north of Lawrence Hill station. The front power car has split from the rest of the train.

The Up Filton line is currently (1430) blocked while GWR fitters from St Phillips Marsh attend the scene.  Once fitters confirm the train is safe to move the front power car will go forward to Bristol Parkway, while the remaining train will return to Bristol TM.

A very unusual occurrence. I wonder if the RAIB will be informed.

An industry wide check on all HST couplers has been put in place this evening.

I'd heard XC were planning to divide and reform some sets to create more capacity, but didn't expect it this soon.

Unusual, or unprecedented? There was the potential for disaster, even if the outcome was mere inconvenience, so I suppose the RAIB will need to be told. If no-one knows whether they should be told or not, I would imagine the default position is to give them a call.

I understand as soon as the brake lines separated it would apply emergency brakes throughout. Lucky nobody in that vestibule at the split, but guess that's unlikely between a power car and coach.
Reports elsewhere the lead carriage was recently back from its C4 work/exam.

On XC sets there is public access to the vestibules at both ends.  At the standard class end there is the bike store while at the first class end you have the usual sliding door leading out to the vestibule.

It is slightly different on GWR sets.  The TM's office is at the standard class end, but you can access the vestibule at the first class end - and there is a toilet there too.

If the brakes suddenly came on and you are in the vestibule, you could be thrown forward - doesn't bear thinking about.

It's unusual...this is not the first time this has happened to a HST (or other T&RS) albeit with altered circumstances. ;)

No potential for disaster...as correctly stated - as soon as the brake pipe hoses are parted the brakes will apply - that is the design. 8)

There are locked inward opening gangway end doors so nobody is getting 'thrown' out of the vestibule Hollywod style. ::)

The RAIB will always be informed & they will advise what actions they require ie. Move nothing/Recover but quarantine/No further action required etc.  ;D

Cant comment further on the rest but you only have to look at the conditon of the bogies and coupler on the coaches in the picture and the powercar to start to work things out.  :-X

I assume there was a robust pull-apart test after coupling up initially - not infallible I know.

Comforting to see that the twist-lock couplers on the air lines parted as per design rather than ripping the hoses from their mountings.  It was a question I asked of my EWS trained trainer when I was learning our air-braked stock.  I have to say that the space to work is somewhat tighter in there compared to one vacuum hose and one steam heating pipe.

The electric socket looks a bit traumatised though.

It had travelled as a minimum Leeds- Exeter- where it separated, since any depot test.

The buckeye pin reportedly failed on the power car. All HST power cars for all TOCs were subject to inspection last night.

The solo power car has now just made it's way to St Philips Marsh.

Family and I travelled on the 0928 Derby to Birmingham (HST) on Sunday.  Was this the same set?
It would have added an extra frisson to the journey had we known what was to happen the next day!

The BBC's version (http://www.bbc.co.uk/news/uk-england-bristol-37839189) of the incident (published two hours ago):

CrossCountry train 'splits in two' near Bristol Temple Meads

The 13:30 BST CrossCountry train split in two on Monday shortly after leaving Bristol temple Meads railway station

A train carrying more than 200 passengers "split in two" shortly after departing from a station, it has emerged.

The CrossCountry service was leaving Bristol Temple Meads when the front car separated from the rest of the carriages, the operator said.

It reportedly came to rest 14ft (4m) away.

A CrossCountry spokesman said 209 people were taken off the train, which was moved back into the station.

He said Monday's 13:30 service to Glasgow was travelling at "low speed" and the "onboard safety systems stopped the train immediately".

"At this stage there is nothing to suggest a similar problem is likely to occur on any other train of this type," he said.

An investigation has been launched.

The Bristol Post (http://www.bristolpost.co.uk/train-split-in-two-after-leaving-bristol-temple-meads-station/story-29859671-detail/story.html) are just as bad:

A Cross Country train at Bristol Temple Meads

A train with more than 200 passengers on board 'split in two' just outside Bristol Temple Meads after an engineering fault.

The 1.30pm northbound CrossCountry train was leaving the station when the front power car became separated from the rest of the train yesterday afternoon.

Automatic emergency brakes were applied immediately and the train came to a stop in Stapleton Road.

It left a 14ft gap between the leading power car and the rest of the train, which was carrying 209 passengers.

The company said there were no injuries, but the detached train caused a long delay, of nearly three hours.

All other trains northbound from Bristol Temple Meads had to be cancelled while the problem was sorted.

A spokesman for CrossCountry said: "The incident happened at low speed and the onboard safety systems stopped the train immediately.

"All 209 customers onboard were safely taken off the train and able to continue their journeys after it was moved back into the station.

"An investigation is currently ongoing into the cause of the incident, although at this stage there is nothing to suggest a similar problem is likely to occur on any other train of this type."

And quite quickly if the max speed for timing purposes is to be believed!

Those power cars can do wonders, without having a load of carriages slowing them down!  ;D

What I found interesting was that both the BBC and the Bristol Post seem to be under the impression that the separation occurred 'as the train was leaving Bristol Temple Meads'.

In which case, the respective parts of the train not stopping until Stapleton Road (the Bristol Post's version), despite the immediate application of emergency braking, would be of some concern.

Blimey - were they pushing it? 44 minutes seems a long time at 168 mph.

Well reported BBC.

About time the railway adopted UTC, like aviation. Imagine.
"What time is the nest train to Parson Street?"
"1432 Zulu."
