Really? I remember being surprised to see semaphore signalling on
the Willesden-Cricklewood line within the past six years or so --
has that gone now? (I know HEx were planning to use that route for
St. Pancras services, but didn't think any work actually got done
on the line...)

There are still semaphore signals at Kew East Junction on the freight
link from the North London Line to the Hounslow Loop, which is about 7
miles from Charing Cross as the crow flies.
