Future for Class 180 Adelante fleets

This idea of putting "more IC-like stock" on the XC 170s routes comes up regularly. Unfortunately it is a really bad idea when you look at the details.

The 170s routes, at least the one to Ely/Cambridge/Stansted Airport, require sprinter differentials to be even close to keeping time. Any stock that can't use sprinter differentials is utterly unsuitable for those routes. This is why they currently use 170s, and why putting voyagers or 180s on them would be a bad idea
Ah, fair enough. It's a shame at least more capacity can't be provided to compensate.

Are those the same XC routes where first class is being withdrawn from December? That’s not very ‘inter city’…
Strictly speaking intercity can just mean travelling between two cities ;)
Regardless, irrelevant to the point that these routes need more capacity and if 180s are unsuitable I will find another suggestion.

Thank you for pointing out that I mixed up what speed limits were what. The point that a train that can't use sprinter differentials is unsuitable for the Birmingham-Cambridge/Stansted route as it couldn't keep to time due to the lower speed limits stands in any case.
Not necessary .
180’s go like stink from the stop to the point that they needed engines derated in the summers to avoid overheating on GWR network .
Much faster acceleration comparing to any diesel stock I know .
Almost matching electric mode but definitely better than diesel mode operated 800’s.

This is still the case now.
I was impressed when I started driving them to find a good unit can keep much the same acceleration rate all the way up to 125mph.

Had the Voyager drive system gone under the floor of the 180s - the traction system is Alstom Onix - then things might have been different. Sources suggest going with hydraulic transmission was influenced by the hydraulic fan club in GWT at the time.
I’m sure this is nonsense. Most modern DMU’s have hydraulic transmissions that work perfectly well. The engine/transmission in the 180 is the same as the 185 which seems to be a well regarded unit. A few months back Ian Walmsley wrote a piece in Modern Railways on the 180’s. I haven’t got access to this at present but recall the general theme was that these are fundamentally decent units but need such as the body side fairings sorting out to improve the engine cooling.

How many 125mph units have this hydraulic transmission?

Out of interest, how were they at Northern? Unlikely that they'd go (No idea where they'd be needed/used) but what was the reason Northern got rid?
The main reason Northern got rid of them was that they were only ever intended as a temporary stop-gap while they were waiting for other trains to be cascaded in.

Makes sense. I wonder if they'd have any use providing peak time capacity on Northern routes? I understand they'd be inappropriate for certain uses as there acceleration vs regular DMUs but perhaps providing less stop services between routes to pull some people off of the main "stopper"?

Maybe this is a long shot, but... a comprehensive overhaul to make them actually reliable? Battery tech? Is there a shot of that happening?

Given their age and perennial reliability issues l'm unconvinced that anyone would spend the sort of money likely to potentially (no guarantees!) achieve that.

One could always go for some sort of testbed, but I am skeptical.

The best chance for a set to escape razorblades would possibly be conversion to replace the aging departmental stock (the NMT and the Sprinters), but that seems rather unlikely.

I suppose it depends wildly on how open access plays out within the next few years, if there's demand for them (especially seeing as theyre ETCS) I can see why the ROSCO might want to bring them up to scratch.

Network Rail may well be after them too, I mean they DID fund the ETCS after all.

Only the GC units are ETCS. The EMR ones (including 110, that was at GC briefly) are not.

Very interesting, many thanks for that.
I imagine if the ETCS equipment has already been designed and commissioned it is cheaper to fit to other class members?
I would imagine so, however Super Voyagers already have some of the required equipment as part of the tilt system, so if could be swings and roundabouts.

Given Grand Central's new trains are supposedly arriving in 2028, looks like the 180s don't have a very bright future....

TfW, Scotrail or new open access operators seem to like a bargain bin option…

(Although I agree that the best place for them is the scrapyard, but until they are there, don’t rule anything out…)

Seen a proposal this morning for a Liverpool to Rhoose open access service down the Marches. They are talking about using 222's (again) so that's a possibility for the 180's.

Or convert them to Open Access sleepers so if they do break down then at least people can sleep through it

Anyone trying to build a new service would surely seek reliable stock though. Starting with unreliable junk could kill a new service stone-dead.

It depends if the price is right, and if they can be put onto less intense diagrams someone might be able to get them to become reliable.

Quite brave to propose this. Fire Service tells you never go to sleep leaving candles lit for a reason, you know.

Of course, could just pull the engines out of them and run them as push-pull stock with 68s. Like some sort of modern-day 442.

I don't think the 180s have had their time just yet. Could they be used for an Orion style service? Diesel units might be more attractive esp if companies (say Amazon) want to push to more greener solutions e.g. rail related. Could also see Network Rail taking them on.

I could also be full of rubbish :lol:

I don't think they're done just yet. Maybe with a comprehensive overhaul, reliability can be improved, and they'll be more desirable. With all these open access operators, it could happen.

Seeing as GWR are now taking on the 175s, do you think it's possible that GWR might actually take the 180s back? Possibly they could be put to work on the Wessex Main Line via Salisbury, replacing some of the rather tired Class 165s? I can't see hurting GWR to take on the 175's developmental cousin (and I suspect there will be quite some compatibility of spares etc).

The Wessex Main Line is only about 90mph max (and usually lower iirc), so that shouldn't particularly overstress the Adelante engines too much.

I think they were probably quite glad to see the back of them tbh, since they went before the HSTs did.

I think there's a better chance of it than the EMUs that have been dumped all this time, there's definitely options its just whos willing to spend a few £ to get them up to scratch. Be interesting to see what happens to the ones at Alstom.

From memory there are some parts which are common to both 175 and 180 (being based on Alstom Coradia series), so possibly could provide some spares to 175s

Mechanically the 180s are not that reliable, but passenger comfort wise they are one of the best. If they are due to be available in late 2028 then I could easily see someone wanting to use them for a decade. Could they be de-engined and used as push-pull hauled stock.

A de-engined version with a modern class 88 equivalent (and they have 3.5 years to build locos) sounds great. I like the idea of Wessex services, Cardiff-Portsmouth and Cardiff-Exeter (now service is split) sounds ideal. It is generally 100mph max Bath-Bristol-Severn tunnel (not 90mph). As far as I am aware 26m units are not cleared south of Westbury (might be Warminster) and Hamble Viaduct is unlikely to allow anything longer than 23m without expensive clearance work.

Grand Central may need to keep hold of some of Class 180s if running the Cleethorpes services, as only 9 sets have been ordered from Hitachi.

They could keep 4 sets and the other coaches go to Great Western Railway to make the 2 car 175s up to 3 cars.

The driving cars could then go in to storage.
