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!

Sir, I see your pedantry and raise you: Did the purchase of BREL by Bombarider extinguish any ongoing liability?

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

There is, but it's rather infrequent in an evening.
Slough times at 1735/1855/2055/2155.
The 703 is hourly to Heathrow and the 7 is every 15 minutes to Heathrow, but more expensive.

The H4 is a hotel hoppa. That's pricey compared with the local buses which serve the Heathrow area with no fare.

With the well publicised ECML problems and now this these Hitachi sets are getting themselves quite a poor reputation already

I wonder if we will end up decelerating instead of accelerating services with them to cope with the teething troubles

I’ll raise that and say the pantographs are manufactured by Brecknell-Willis, who are now part of Wabtec.

Your move!

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

Rest assured the delay minutes will end up at Network Rails feet, always does !

Look - lets just agree to blame Dave the fitter. It will be cheaper and easier!

can they?

Some 390s were fitted by Alstom with monitoring equipment (cameras at least), to help diagnose faults in the WCML OHLE interface.
They are the ones NR uses on test runs on newly electrified routes in the northwest, and I think the 390s with the facility have it running continuously.
As a result of that, the same capability was written into the IEP spec (and 387s and probably all new-build EMUs).
I think all the 80x units are capable of doing it (if switched on!).

Latest from Network Rail. As part of the repair work, tonight from 21:00 all lines will be blocked to electric traction between Southall and Acton West. The main lines will be closed with all trains using the relief lines. All electric only services will be cancelled unless substituted by class 165/166 units. All class 800/802 formed trains to run on diesel mode between Reading and Paddington.

Definitely an argument for having bi-modes!

Some Pendo's have cameras fitted. None have any instrumented panto graphs or technical kit. They do monitor but not in the way i thought you meant.

This event sounds very bad. Does anyone have any piccies?

The benefits of not having cheap 1990's head-span OLE

My understanding is that the cheap [and cheeful] 1990s OHLE works quite well if it, and the trains that interface it, are well maintained. There seems to have been, quite predictably, a lost of corporate knowledge in the handover. Railtrack destroyed all the adminstrative records which didn't help and then there was a further handover to network rail.

Had the knowledge been retained, there might have been better maintenance of the assets and less motive to introduce new overengineered and unaffordable systems.

Perhaps then we would have electric trains running to Bath and Bristol by now.

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.

If GBRf were running as GBRf then it was be treated as their (FOC) minutes. But I would think here that they are acting as agents for Hitachi, who are testing on behalf of GWR.

Separate from this I would expect there to be compensation arrangements between the parties, but what would happen from them would depend on what the contract says. Given the likely size, I expect someone will be claiming from an Insurance Policy.

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.

AFAIK Hitachi do not have their own Track Access Agreement. Therefore the delay will be down to whoever's TAA they were using.

The FOC is GBRf for Hitachi "test" runs. This offending working has been described as a "test working" so GBRf will be liable.

Has the offending path been deleted from RTT? I cant see a 5Z65 on RTT?

Cheers. GBRf better hope it wasn't a driver error then.

Maybe he/she wasn't steering carefully enough and the pantograph wobbled outside the envelope.

BBC Radio 4 news bulletin at 6 p.m.- 'a limited train service is running to Paddington and beyond'. Good to hear they got special permission to go down the Crossrail portal! :lol:

londonmidland · 17 Oct 2018

Seeing as the damage occurred on a headspan structure, would it be immediately replaced with, what I assume was going to replaced with anyway, a portal/TTC structure, or would that require an overnight possession to take place?

That would also require work on the foundations, which means design and calculation work is needed. Not something you'd want to do when trying to get significant damage repaired ASAP.

Also in the same bulletin, a passenger at Reading ranting that they should nationalise the railways. If only they knew it was BR infrastructure that caused or exacerbated the incident (and frequently causes problems on the ECML)

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

Err I think you may have mistaken Marlow for Marylebone?

Tio Terry · 17 Oct 2018

Just a thought.

Pantographs have to meet the design requirements of the Energy TSI and it's highly unlikely that any new train would not do so. That points the finger at the existing OHEL infrastructure which was probably designed and installed well before the current Energy TSI was introduced. The question then is who allowed the Test Train to attempt to use the non-compliant OHEL? Or was it human failing in that somebody decided to raise the pan without first agreeing it?

irish_rail · 17 Oct 2018

Pan must be raised below 20mph except in designated areas so for the drivers sake I hope that's not what's happened

My wife muttered "stupid remark" at that particular passenger's comment ...

I think the actual quote was "Why don't they just nationalise the railways?".
As though a change of ownership will instantly solve all problems.

I was looking at that today, somebody else mentioned 5Z64 which had its Paddington - North Pole leg cancelled on arrival at Paddington.
I can only presume that it was decided to send the unit back to Stoke Gifford direct from Paddington and that 5Z65 was a VSTP path submitted by Control or Hitachi’s Central Planning Cell.

Because the incident happened at Hanwell, so wouldn’t gain anything going via Greenford; and there are (Thsnks for the update. Some news

Just seen the reply, thanks.
IIRC someone on the radio said it was East of Ealing Bdwy, hence the question

Looks like a sensible suggestion to me. High Wycombe and Marlow are only 5 miles apart.
