Dipping into the BBC» Local News revealed the following- https://www.bbc.co.uk/news/uk-england-56902528Perhaps some of our industry insiders have more information? It's just as well this has come to light (and hopefully will be resolved) in current circumstances when traffic is light. |

If this was an isolated problem, I would be at least somewhat forgiving.
However taken together with all the other faults and failures, these are starting to look pretty rubbish.
Failure to couple and uncouple reliably, despite this being an "essential requirement"
Failure to cope with the waves at Dawlish, also an "essential requirement"
Overheating in hot weather.
Poor ride.
Unreliable toilets.
Unreliable reservations.
Poor quality trim and fittings.
And a general failure to meet the required levels of availability that resulted in frequent short formations, forgotten about with the reduced passenger numbers in the pandemic. But no doubt to return.
The poor standards of passenger comfort and facilities are arguably due to the TOC▸ policy of "what downgrades can we get away with" and not Hitachi's fault, but still gives a poor impression.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU▸ is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

There is another problem begining to occur with wrong side door releases. When the driver initiates a correct side door release, there have been a couple of instances when a door on the wrong side has been released in addition.
That’s a potentially very serious issue, though I’ve not heard any reports of it happening. Are you able to provide any more information? I agree, this is a most serious failure IF the reports are accurate, which PERHAPS they are not. I would expect reports in the national press, but not aware of any such. And howls of outrage from the RMT▸ , not aware of that either. The opening or releasing of doors ONLY on the wrong side, might imply operator error, but the releasing of doors on BOTH sides suggests a serious defect as this AFAIK▸ cant be done by mistake. |

Roger Ford has an article in Modern Railways (next month's, presumably) about the repairs now being tested by Hitachi on 802007. This is available to read on line free but rationed. In his e-preview he says: 800 Series modifications in close-up
Hitachi’s solution to the various fatigue and corrosion cracking problems in the bogie bolster area of the 800 series vehicles began test evaluation in January. We featured a photograph of the test train – 802007 - in our News section last month.
Now, an alert reader has spotted the test train and taken photographs of the modifications. Two vehicles have been fitted, a Driving Pantographs Trailer (DPT) and the adjacent Motor Composite. Different designs of replacement yaw damper brackets have been required for the leading and trailing ends of the DPT. So there is plenty to consider.
To put the 800 series modifications in context, the column also features photographs of other manufactures’ designs for the interface between the yaw damper and the body-shell for 125 mile/h DMUs▸ . My thanks to my colleague Tony Miles for providing the illustrations.
Compared with their peers’ designs, Hitachi’s revised solutions, particularly on the DPT, are decidedly chunky. However, it is important to bear in mind that these vehicles are part of the Intercity Express Programme (IEP▸ ) - a 27.5 year Train Service Provision (TSP▸ ) deal. So now is the time to make sure that the problems has been cured once and for all!
So the next thing to look out for is the decision to go ahead with repairs (or not!), and then the plan to do it, how many units will be out of the fleet at a time, and how long it's all going to take. And eventually whether it's really sorted the problem. |

Note that the reports refers to the IETs▸ as being "DMUs▸ " I seem to recall being criticized for referring to them thus, with IET supporters stating that they are not REALLY DMUs but actually something else.
It was suggested that DMU was a negative term that people linked with shorter trains, no catering, and general downgrading.
Moving on from that, I thought that new trains suffered from cracks in three locations, these proposed repairs would only seem to deal with only one such set of cracks.
I presume that hitachi are not paying any significant compensation for the ongoing lack of availability of these trains. Or providing some extra units free of charge to make up for this.
Meanwhile 5 car units instead of full length HSTs▸ are the new normal, better get used to it, as Cross Country customers have got used to the reduced capacity of new trains.

I have heard reports of such an incident, I can’t remember if it was on GWR▸ or another TOC▸ . All doors released correctly on one side of the train but the TMS showed a door had also incorrectly released on the wrong side of the train. I can’t remember if door buttons armed or wether it was just a TMS glitch. |

I did see 802007 out and about on a test run in January - you can see the modifications and sensors attached to them which were feeding an army of laptops and boffins information via cables that run through the adjacent doors. |

ORR» have published their final report, plus related material, on the Hitachi train cracking problems. This does explain in some detail what happened, both in the organisations involved and in the train bodies. It doesn't address (and probably never could) some of the "why" questions, such as why the corrosion environment for Japanese trains does not lead to stress corrosion cracking. The contribution of track, as worn, and wheels, ditto, to the anti-roll bar and yaw damper motion and forces is also still a big vague. The outcome is a six-year rolling repair plan for all the affected trains, including some bits (e.g. coupler mountings) where cracking was only found in the later more through investigations. They also display a rather touching belief that more standards would prevent such things happening.

A SIX YEAR rolling program of repairs presumably means ANOTHER six years of short formed trains and reduced services. And that is optimistically presuming that the repair process runs smoothly and to time.
The rush to scrap existing stock means that opportunities to use alternative rolling stock will be very limited.
I cynically assume that Hitachi will not be paying compensation for their failure to meet the promised availability.
And after this multi year rectification process, they will still be nasty suburban units unsuited to inter city routes.

A SIX YEAR rolling program of repairs presumably means ANOTHER six years of short formed trains and reduced services. And that is optimistically presuming that the repair process runs smoothly and to time. Obviously the more you do at once the shorter the overall time, and vice versa. The practical limit of units that can be under repair at a time is also obvious: one. The programme is described as: Hitachi and its industry partners are about to start the major programme of work to repair 1247 Class 80X vehicles and a further 487 Class 385 and 395 vehicles. This recovery programme is expected to take place over the next six years. It is structured to minimise service disruption by taking the minimum number of vehicles out of use at any one time, coordinated with other planned maintenance activity on the vehicles. That's four and a bit vehicles per week. For some reason the work is going to be done at Arlington Fleet Services at Eastleigh, where there will be two repair lines. Whether that means doing one five-car at a time in a week, or two units at once and taking longer, I can only guess. Further details revealed are: The programme will address trainsets containing vehicles with cracks first, prioritising those with cracks in the vicinity of the yaw damper. All vehicles, whether cracked or not, will be modified, with the programme expected to be complete in 2028. The rush to scrap existing stock means that opportunities to use alternative rolling stock will be very limited. True, but that's the world of fashion, isn't it? I cynically assume that Hitachi will not be paying compensation for their failure to meet the promised availability. I wonder. Obviously the whole repair programme is Hitachi's cost, and they have not been paid for trains not presented to the TOC▸ as required in the TARA▸ . But clearly a refund of the lease cost per diagram is inadequate compensation; it's not as if GWR▸ can whip out their StockShop app and hire an alternative unit for the day. I imagine the TOCs (or in practice DfT» ) would have a legal case for breach of contract. That would depend on what's in the TARA and MARA▸ , and I suspect in the blacked out bits. |

Had most of the HSTs▸ not been scrapped in such a hurry, then alternative trains WOULD have been available.

Presumably hitachi staff are not going on strike.
And will therefore be able to use the strike days to catch up on routine maintenance.
Over 30 short formations again today.

There were over-running engineering works in the BPW▸ area earlier this morning which may well have affected the Hitachi depot
