The sprinters and pacers will struggle on till the Turbo stars and Pennine Desiros relieve them
Really? I'm aware of the planned electrification programs, but that won't cover the various branch lines and other secondary routes. With the Pacers and Sprinters now approaching 30, and cascaded stock will surely be unsuitable for the services in most cases (cascaded Intercity stock won't be suitable for branch lines), I'm sure some DMU's will be needed within the next 10 to 15 years, won't they?

However there are no prospects for DMU orders in the foreseeable.
Surely it's only a loss of 35x class 153, assuming class 155 life extension is viable in which case you reform the 70x class 153s back into 35x class 155 units.70 x 1 car DMU withdrawn.

If the electrification work continues it is entirely possible that all of those units could be replaced by electrics.
The "residue" of 'non-electrifiable' lines probably requires fewer units than exist in the Class 170 fleet alone.
Note that we'll need 500+ additional carriages for extra capacity over the next five years as well replacing the 278 DMU carriages. I don't think the electrification plans will result in 800+ additional carriages by the end of 2019.
We will need?
Or just like?
In the case of Northern, TPE and FGW the answer is definitely 'need.' They haven't had much of their promised extra capacity that they were supposed to get in CP4.
I don't know about Southern, FCC and SWT who are also due to get extra carriages as I've only ever used South East operators at the weekend.
Unless of course you can find a way of getting extra passengers on to full and standing services like that 07:17 Manchester-Chester which gets a loading of 260. The service is booked for a 2 car 150 but a 2 car 142 is not unknown to turn up without extra capacity. The next service isn't until the 08:17 Manchester-Chester for when a 142 turns up which can't load 260.
If only a handful of services are massively overcrowded then all those passengers must bear the £3m cost of each new unit themselves.
The money that is saved by struggling on can be spent accelerating said electrification programme.
DMU's/EMU's for short local services,longer hauled services some up to date coaching stock and a 68 on the front.It seems the UK has a bit of a problem with this whilst the rest of the EU can manage loco hauled passenger services no problem!
I take it you've never been made to wait an hour for the next service due to an hourly being too full to take any more passengers?
The DMUs replaced by EMUs will on the whole be kept in service for the foreseeable future, unless new DMUs are ordered. Network Rail are set to lengthen many platforms on non-electrified lines during CP5, there are also schemes like the Todmorden curve which have been committed to which will need additional diesel stock, while the Ordsall Chord will see a mix of diesel and electric stock. There's no point building the infrastructure for longer diesel trains and more diesel services if the carriages aren't going to be there. This seems to be something you don't want to want to know about because it doesn't fit in with your dream of diesel trains all being replaced by electric trains.
So you claim that lots of DMU vehicles are going to be available thanks to being relieved by EMUs, and then complain that there will be no new DMU vehicles available?
TPE-North is going to release an awful lot too

So in summary the additional diesel services/capacity can be provided by DMUs released by electrification. However, as Angel Trains are planning to write off the 142s in 2019 and Porterbrook are planning to do the same with the 153s and will significantly reduce the class 143 and 144 capacity (if they remain in service) it means new DMUs will need to be delivered in 2019, otherwise services will have to be withdrawn or have their capacity cut back.
They'll still be a number of DMUs needed on the current North TPE network. There are no plans to electrify Scarborough, Middlesbrough or Manchester to Liverpool via Warrington. Hull-Manchester looks set to remain a DMU service in CP5 (ahead of likely electrification in CP6) and the diesel units used on that line will likely be needed for overnight services between York and Manchester Airport. This is because overnight services need to go via Wakefield Kirkgate and Brighouse for route retention purposes during engineering works.
They are only planning to write them off because they will either have to refit them to PRM-TSI or withdraw them, since the former is not feasible they must chose the latter.
They will not have to withdraw them if they are granted an exemption from the regulations for the next several years after 2019.
There is no absolute need to withdraw then in 2019 and not say, by the end of CP6 or whenever, by which time electrification progress should have obliterated any need for diesel services on TPE or similar.
287 DMU vehicles being withdrawn because of PRM TSI is £430m worth.
Where will this money come from?
For context I make Middlesbrough-Northallerton via Yarm roughly 32 route kilometres, so 64 track kilometres, or ~£100m to electrigy.
Where's the nearest brick wall?
Post 184 I gave reasons why effectively 278 DMU vehicles will be withdrawn by the end of 2019 and in post 187 you said electrification will be able to replace them all, but that assumes practically no additional services on unelectrified lines!

You have not yet explained how you to plan to pay for all these new units that are going to have ten years of front line service and then have nothing to do unless you want to send still serviceable units off to the scrapline early to make room for them.

Even if you can only withdraw half the fleet that is still 25 extra units for capacity enhancement elsewhere.
For context I make Middlesbrough-Northallerton via Yarm roughly 32 route kilometres, so 64 track kilometres, or ~£100m to electrigy.
Manchester-Liverpool via Warrington comes out at about 85 track kilometres, so ~£127.5m
Those two projects alone significant reduce the number of diesel units needed for Northern and TPE.
Every Class 185 freed is £4.5m saved (as we are going to be swimming in 100mph Electric Units).
That'll be convenient with all the reversals on Norwich - Liverpool...
Umm actually it presents no major problem at all as a design is already proven to work quite succcessfully
Chiltern AND Arriva Trains Wales as did DBS when it was EWS all operated Class 67 hauled rolling stock with DVTs at one end so how can you say there be problems on this route - only problem is getting the rolling stock.
Surly the most sensible option is to build new DMU's to operate on lines like the West Highland, Far North/ Kyle of Lockalsh, Cumbrian Coast, Cambrian Mainline/Cambrian Coast etc. Routes that are unlikely to be electrified in the next 30 years so will need new build diesel stock eventually which could free up 156's/158's for use elsewhere until they are freed up/replaced by electrification.
So we're incapable of building a type of DVT to operate with loco hauled services then?
