As I understand it, it's shortage of rolling stock which needs

I don't think it is lack of rolling stock, as there are sufficient
units spare (for starters, all three class 508s are available) to
run at least a Euston - Willesden Jcn shuttle. However, there
would be a probably be a lack of paths between Queens Park and
Willesden Junction due to the increased Bakerloo service at
least during the peaks.-

I was just gonna say, presumably the 508s can't be used for any
services other than into Euston, and with so many lines closed,
there
can't be a shortage.

Can't Watford Junction to Stratford be done entirely on DC? (There's
a
dual-electrified stretch where the 313s normally switch to AC, but
presumably DC can still be used.)

(Not that there can possibly be a stock shortage. If there's enough
stock to run the normal Euston-Watford and NLL services, then there's
enough to run Euston-Watford as normal and Stratford to Willesden Jn
going via Primrose Hill instead of West Hampstead.)

The reason why the trains switch to AC is because trains using the DC
stretch along there would have to go at half power.

Isn't that just a general feature of the 313s? As built for the GN they
ran in series only on DC because the Northern City Line section is
limited to 30 MPH anyway. It doesn't affect the 508s and I thought the
313s transferred to the NLL/Euston Watford Service were modified.
