Of course where we share with BR then their signalling practices are

Only when it's their track.
Where do tube or sub-surface trains run that is strictly NR territory?

Queen's Park Junction to Harrow and Wealdstone.
Gunnersbury to Richmond.

There *are* true LU three- and four-aspect signals on the Metropolitan
Line north of Harrow-on-the-Hill.
I thought those would be NR signals. I notice that they still have the
separate stop arms for LU stock and AWS for NR stock.

Nope, they're LU. It's LU track.

Are you sure about AWS? I thought that all stock running on that line
had to be fitted with tripcocks.
