Reading the rest of the article, it's a pity they don't make use
of the dual system capability to use overhead AC on the Euston
approaches and simplify the layout there by chucking out the DC
electrification when the changes ahead of HS2 are implemented. I
was amazed to see they're keeping the dual voltage tracks through
those changes.

Yes, it is strange. Perhaps there isn't a suitable voltage change point
on the Euston approach?

I note there are tunnels north of Euston which are only
DC-electrified, just before the dual-electrified section starts.
Maybe they are the problem? Can't the 378s switch while on the move?

That's the bored pair of Primrose Hill tunnels. I suppose they are too tight
for 25KV overhead electrification?
