Disruption between London Paddington and Slough 16/17th Oct 2018

[lord rathmore]

OHE seems to do a great job in Switzerland, Austria, Germany, Italy, etc. Does seem that most of the 70s,80s & 90s electrification here was done to a tight budget.

 

[hwl]

So does the picture evidence confirm that the Pan was incorrectly maintained on the 802 or does it just show it as damaged due to the incident? If incorrectly maintained, I presume no quality of OHLE would have prevented yesterdays events

Just shows most of it missing (normal in these cases)

 

[SWT_USER]

Who gets landed with the delay minutes for this one, Hitachi?

 

[Pete_uk]

As its a 802 would the cost fall differently than if it was a Agility 800?

 

[LNW-GW Joint]

Portal wiring is not a panacea for dewirements.
The original WCML wiring is all portals, but still suffers 4-track closures at times.
The culprit is often neutral sections which seem specially vulnerable.
Both WCML and GWML wiring can be monitored en route by 390/80x trains.

 

[swt_passenger]

Who is hettige landed with the delay minutes for this one, Hitachi?

Please explain?

 

[SWT_USER]

Please explain?

Apologies. That is absolutely awful

I meant to say, who gets landed with the delay minutes for this? Will it ultimately be Hitachi?

The TOC. Hitachi cannot be attributed minutes.

Maybe Hitachi (and other rolling stock suppliers) take out liability insurance for operating issues attributed to failures during testing that is under their control.
After all, it is the nature of tests that there is a potential for failures otherwise there's no point in running them.

I suppose that they are dynamically different from straight conductor wiring in that they induce disturbances in pantograph/wiring movement so represent a more likely failure point.

Well that may be true for the OLE over the track on which train in question was running on, but the other three lines might not have been totally trashed at the same time. The probelm is that with headspans, the damage to one of the lines upsets the tensions across the tracks holding the other lines in registration. The next train that comes along is then running under faulty OLE and liable to pull it's own wiring down.

I'm sure that OLE does fail in other countries, but it is hardly headline news in the UK. I can just imagine the reactions from most UK TV viewers to a report on the 10:00 news about thousands of Munich commuters being late home because of a dewirement.

Last night one my way home from Marlow, had to get the 4 bus to Slough, then the 81 bus then h4 bus to Heathrow, then the Piccadilly and Circle line to Victoria.

This morning the same journey but in reverse.

Maybe there was a better route?

 

[SWT_USER]

The TOC. Hitachi cannot be attributed minutes.

Yes but if it is a rolling stock fault wont they ultimately be responsible so GWR will pass on the cost?

I appreciate this is different to availability of units which Hitachi are responsible for, just curious.

 

[JN114]

The 802 wasn’t being operated by GWR - the unit in question has yet to be commissioned into the GWR fleet.

 

[Requeststop]

Seems like some services are back: the 14:03 Paddington-Penzance has made it from Paddington to Reading on time.

 

[Roger100]

Electric trains are now running out of Paddington on the relief line, and into Paddington on the up main. Possibly other lines operational too. Heathrow Express has resumed operation.

 

[sarahj]

I've been delayed in munich due to overhead issues. As a note, the DB stopped using cross-spans or head spans on new works from about 1974. When I pointed this out to someone high up in BR involved in the ECML electric works I was given a 'we know what we are doing' speech. Anyway, here is a link to a video of a German train bringing down some OHLE.

Good point. The train operator was GBRf.

 

[FGW_DID]

Why not? Hitachi have their own people in the ICC at Swindon including someone dealing with Delay Attribution. As already mentioned there was no TOC involvement in this.

 

[JN114]

I just hope that the TV people weren't filming 'Paddington' again - it's already a terribly boring and repetitive programme routinely showing just how many times there are problems out to Reading !!

They weren’t in route control last night - as far as we’re aware filming is finished.

 

[DarloRich]

Both WCML and GWML wiring can be monitored en route by 390/80x trains.

can they?

 

[Hapana]

Train from Marylebone to High Wycombe and bus home from there?

 

[Dr Hoo]

Good point. The train operator was GBRf.

There are often train testing and commissioning track access agreements with their own ‘simplified’ performance regime. Sound like this one won’t (directly) involve GWR.

By that example, who foots the bill every time a Class 91 brings down the wires between Newark and Retford? I am sure it's not BREL

I'm sure there's a direct Greenline from Slough to Victoria?

 

[FGW_DID]

the 387s have got a "pan cam" so presumably that's what LNW-GW is referring to.

But BREL have:

a) handed over the product to the operator
b) ceased to exist

Thanks - monitoring in the widest sense rather than monitoring in Mentor type sense.

Of course not, It's the TOC who would be operating the train at the time!

In the case of last night, the 802 was not being operated by a TOC, it was being operated by Hitachi utilising a GBRF driver.

 

[43096]

But BREL have:

a) handed over the product to the operator
b) ceased to exist

Ah, but a) BREL is now part of Bombardier and b) the 91s were a GEC-Alsthom build; they sub-contracted BREL for assembly. So perhaps “Megafuss” should be going after Alstom!
