I think the air con units on all trains would have been struggling in recent days. If people could be trusted not to open the windows train builders could install hopper windows on all trains just in case the air con did fail or was without power for a length of time.
In 12 years of using Desiros I've not had an aircon failure.....
Complete failure across a whole unit is pretty concerning, especially as this is meant to be the blueprint for the fleet.
Some 379's have had broken aircon over the last few days which by all accounts was rather unpleasant.

That's impossible! According to some particular individuals on Twitter those 379's are utterly brilliant simply because they are relatively new and were built by Bombardier (I'm sure you can guess who on Twitter).
Really, still? I think you're really stretching 'misinterpretation' to the limit there...
A/C failure across the board on a sealed train is nasty. That being said there've been several reports of A/C failures on c2c's 357s and I was on a rather unpleasant Southern 377/3 earlier this week with the A/C switched off, so it's not exactly rare. Can't comment on if I've ever had a Desiro with the A/C failed. I don't recall that being the case, but I could be wrong.
I believe it was a test bed to see what works and what needed further work. If they fail regularly once the complete overhaul has been completed then I would be concerned.
Er no, I had a discussion with the relevant person/people on Twitter about the fact the 379's are only a few years old and are already starting to fail. To which I was met with a barrage of tweets saying how good they were and that the "skips" are rubbish etc etc. The fact that a few people who troll the GA twitter feed seem to be connected with Bombardier seems to have something to do with it.
I dont think GA 317s have much more life in them, neither do ours (London Overground) 'Under the hood' they are completely knackered now. Most of them have fried electronics racks, fried traction motors, fried WSP racks, and fried circuits. None of which are being replaced just patched or borrowed from healthier units. Ilford usually and have said for some years now that alot of it is down to most of the 'big' bits like Thyristor packs and traction motors are near impossible to source these days for such old units. It hasn't helped either that NX/GA ran them into the ground. No new paint or seat covers can hide that. The bombardier demonstrator 317 now lives in ilford for some reason, and all of the ex airport 3177XX units that we now have at LO are almost useless, although the internal refresh that was done on them was nothing short of a miracle and has been well recieved. But 90% of our failures on LO come from them.
315s on the other hand are quite different. Although they look dated and are technically the older train, these are far from finished. They just seem to go and go. The C6 overhaul they had shows and they have superior systems like circuitry, wiring, cabs, doors, egress, aircon system (for drivers),WSP racks and it certainly shows when its slippery. The new PIS system works and isn't prone to failure. Failures are few and far between. Although these have been hammered too they haven't fared nearly as badly as the 317s. The main things to go on them are the electric doors (which can be easily reset) GSMR radios (which are new anyway) and maybe the odd air leak from a sticky valve. Things that can be patched up relatively easilly. Ive still yet to fully fail in one in 7 years, to a point where I cant move. 317s on the other hand...
I think if somebody took the time to do the 317s properly from the ground up eg retractioned, replaced the braking systems, decent aircon and PIS systems for passengers you could probably squeeze another 10 years of good service out of them because thats where the age is starting to show...Some of the units histories in their fault books you would wonder how the train is even able to move under its own power. But after the bombardier demostrator, which I would hardly class as a success I think that will be unlikely to happen.
Cant speak for 321s as I have no experience with them but their demonstrator looked quite smart.
I don't think the argument is that the 321s can't be refreshed, just that even if they were they still wouldn't be adequate for running GEML services all the way up to their actual expiry date. A line that I seem to recall seeing in one of the NR reports (Atkins report maybe? I forget) is the suggestion that the 321s could be isolated to branches (e.g. Harwich, Walton, Southminster) and the Southend Victoria line, avoiding their use on the actual mainline in regular service thus avoiding the interference of 110mph traffic with 100mph stock.
This I'm guessing would need a fleet of around 50 units, leaving around half to be cascaded to wherever, presumably the North. That leaves a substantial enough fleet to be realistically used on both sides. The 321s will also presumably also only be able to be refurbished properly at any reasonable pace if there is additional stock on the route to cover for their absence given things are so tight at the moment - so presumably they would be sweated out until the arrival of some new units before doing the bulk of the fleet.
The 317s on LO by all accounts are still every bit as unreliable as they were on AGA, unsurprisingly, which rather hints at the state they're in. Perhaps they can be brought up to scratch, but they do seem more of a problem case than the 315s.
The 319s on NR have, as far as I can see, a pretty poor reliability record thus far too, but I rather suspect that can improve once they're more familiar up there.
HH: interesting, I didn't realise that happened, perhaps that explains why they have so many traction motor failures compared to other units. That being said I was on a TfL 315 yesterday that was missing the rear motor pair - it was noticeably slower - still ran to time though.
I agree with you somewhat. The 321's with a very good refurb could see out the decade they have left doing the Harwich, Walton and Southminster branches. If a decent fleet of them were kept being maintained at Clacton with enough of them to ensure any small faults could be fixed instead of needings to be put back into service constantly. I think the mainline needs a fleet of 360 type units be that a new fleet or cascades.
According to certain people though the "skips" are only fit for scrap. They also say that *every* train on GEML should be a class 1 headcode (including all Harwich and Walton services) merely because GEML serves the city. And by that notion GEML should always have a new fleet to be cascaded to less important lines. I mean the pure arrogance of that is astonishing. Yes GEML has not had the investment it deserves which will hopefully be rectified next year but to say that every train should be a class 1 headcode and have the newest best stock is frankly ridiculous. Considering the patchwork quilt GEML has for infrastructure I rather think the emphasis should be placed more on Network Rail to get it sorted, as even a completely brand new fleet wont speed up journey times or stop the current delays as most are caused by congestion and infrastructure faults.
