In terms of ambiance they are basically just a 4-car Class 150. But they are much needed additional capacity. I'm sure Northern would equally happily take the same number of Class 150 vehicles, but they're just not there for them to take - otherwise the project wouldn't even exist.

Overwhelmingly it's about delays to, and cuts in the scope of, electrification (including e.g. Windermere and Notlob - Wigan) - and the general DMU crisis, if I can call it that.

Well I for one am rather glad that they have de-scoped the electrification of Notlob. :s

Just a quick question--unfortunately 84 pages is too much to look through right now--when completed, is a 769 a totally universal train, i.e. it can run from wires, 3rd rail or diesel without any changes?

I think the GWR ones will be so that they can run the North Downs services. That will be subject to signalling/TPWS issues.

I mean, they aren't removing the OHLE or 3rd rail capabilities, right?

Almost universal. It won't get very far under the Tyne & Wear Metro's 1500 V DC OLE. ;)

I think the Northern ones will have the 3rd rail shoegear removed? Do the 319s at Northern have it removed?

Yes Porterbrook says there's no point retaining the shoegear on the off-chance they might run on 3rd rail in the future.

Yeah, it's just a pain as they would just keep getting knocked off by high ballast.

Off topic (apologies), I am now very worried about the average age of the members. I'll get all 769s painted Norwegian Blue.

Could be the new name for the blue around the cabs and doors! It is very close to the blue on their flag anyway.....

Not sure how that would work, considering the Class 319 is an integral structure so you can't just put a new body on the chassis as you might do with a Mk1-based unit as was proposed for the 424.

The ends could be rebuilt as something resembling a class 317 or 455 to give through gangways. Alternatively, a proper driver's cab such as on the class 325 (which is the same basic bodyshell as a class 319* with a networker front end). Any othere internal reconfigurations would only be subject to the doors layout, as it the case for modern units.
The wide loading doors are different with suitable additional body and floor strengthening.

It is just a 319 with a networker cab, buffers, no windows, no interconnecting gangways and the sliding doors replaced with roller shutters. Also they have no seats but it's a parcel units so what did you expect?

A 325 is identical to a 319 except for the cab and the body. So they're both trains then. I'm surprised anybody can tell them apart.

Not exactly as they proposed to keep the 319 body and just create a new cab design.

I was thinking more in the "fool the public into thinking it's a new train when the guts are still the original" sense.

The 424 would have been a crashworthiness upgrade though.

To be fair the original plan had more than just new ends, they were to have totally new modern interiors and air-con. So much for all that then.....
