Indeed there is/was, using a wireless communication device, in the same place that Electrostars have their top headlight/line light:
Thanks for the tag, but it’s quite an old one and found out the answer (and shown how it works) since - it works via Bluetooth.

While it at least will have been useful as a testbed for such new technology, it is unfortunately another part on the GWR 769 program that is now a waste - the trackside bailses being another.

SWR's service on the West of England line of late has been absolutely diabolical, its become a local joke amongst the passengers, when the landslip happened at Honiton and SWR threw the towel in, GWR still ran the one train a day and an additional return working, one passenger from Feniton asked me if GWR were taking over the route, his exact words were "Even you lot are f**king better than that shower" (referring to SWR), to which I chuckled and replied that I'm sure there was a back handed compliment in that statement somewhere!

Uff. Must say that's pretty depressing - haven't had the need to take that route ( despite it being the nearest ) since before 2020 when it was still ok. What a pity.

The connection is WiFi not Bluetooth. It doesn't use balises as there is no balise reader on a 769.

They’re a lot less complicated - they only operate on diesel, as opposed to diesel and third rail with the GWR units. They also don’t have the ASDO beacons to contend with
That's not really the case. It's the diesel side of things that has caused the most problems for all the 769 operators - certainly until a major firmware upgrade improved things dramatically. Running on DC or AC has caused GWR very few problems. The only real issue I can think of was to do with the auxiliary power supply failing on passing through an OLE neutral section when in AC mode but that was resolved with a software upgrade.

If by beacon you mean a balise, the 769 ASDO system doesn't use balises, just GPS.

When/if it dose arrive (not likely at the moment) will be table seats on the train??

Half life, not old.

A battery electrostar is possible but would drop 110mph to 100mph.
Well they are showing wear anyway

Which train are you talking about? The 769s don't have table seats as evidenced by this video
Watch until 0:28 where they show the inside through the window and how it doesn't have table seats. In addition, this seating diagram also shows no evidence tables except in First Class, however, this was dated April 2021.

That's two more citicisms of them based on false assumptions safely put down. :rolleyes:

Cheers for the free eye roll, I was going on what I was told during their modifications at Eastleigh works (in the test shed if anyone really really wants to pin point it). But :rolleyes:

Anyway, thank you @TurboMan for the correction, not that it changes the point about the kit now being wasted.

Other than there is no waste on redundant balises because they didn't exist.

I'm going on the North downs line the day after tomorrow so hope to see evidence of 769s

"Optimist of the Year 2022 " award goes to.................... :lol::lol:

Apart from the aforementioned signage, the only place you'll see an actual GWR 769 is if you take a trip past Reading TCD (or Oxford Carriage Sidings).

I understand there are bits of operating signage relating to 769s.
Yes, there is a switchover one at Reigate (ether may also be a car stop marker for 769s as well, but I can't quite recall), I wonder when it may be removed.

There isn't any point running anything down the line with a 769 anymore. As other members have hinted, you'll just see signage.

Given the need to remove is pretty much limited to just 'tidiness', it may yet linger on for quite a while!

Given how much FGW, and even BR, signage remains on the GWR network to this day, I wouldn't be surprised in it's still there in a decade's time.

Although said First Great Western (FGW) signage may be of use, therefore no need to replace it. However the 769s' have no requirement anymore, but I do agree, they'll be there for some time.

I'd say a sign that's still in use would be a higher priority to update to a new TOC/standard than one that has no operational requirement.

Barring a station rebuild or particularly pedantic member of staff, a redundant sign that causes no operational issues could well last indefinitely.

The majority of it is station signage, yes, however I would argue letting it remain as they have is damaging to brand image, whereas 769 signage make little difference. There are also countless HST stop markers litered across the GWML, which considering GWR no longer runs 2+8 HSTs, or even HSTs at all in the Thames valley, should give a fairly good idea of how little enthusiasm there will be to remove the 769 signage.

Maybe the sort of thing that could end up in a charity auction. Would be good for a giveaway on the class 769 farewell tour.

Speaking of once they are gone I get the feeling the signs might actually disappear without intervention from NR or GWR at the hand of 'enthusiasts'. The same did happen to the HST signs around me, the ones I mentioned that remain are the ones in more difficult to reach positions off the end of platforms.

They’re a lot less complicated - they only operate on diesel, as opposed to diesel and third rail with the GWR units. They also don’t have the ASDO beacons to contend with, and I don’t believe there was much in the way of disputes about the cab designs.
The complicated bit was retrofitting the diesel alternator sets they ran perfectly well on DC or AC for 30 years

NR still haven't removed DOO mirrors from the Southern network 6 months since the 455's were withdrawn so I can't see 769 signage being removed anytime soon.

The GWR ones have an additional bus to other 769s so 3rd rail is kept.
Im not sure that is the case they all have the additional bus because the motor alternator sets ate on a different vehicle to the choppers/motors and they aren't allowed to use the running rails as a return path because the running rails are bonded for small signalling currents only.

West is best

And on non-electrified lines, double rail track circuits are used, which means IRJs in both rails…
So all such 769 units would need a return bus to be installed.

If you look closely you can still see occasional pieces of broad gauge track, often used as posts for signage or fencing.
