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.

The Barking-Gospel Oak line still has some mechanical working around
Harringay. Harringay Park Junction's starter is still semaphore, mounted
above Upper Holloway's distant. I think most of the T&H is now TCB, but ISTR
reading in a magazine article that there are one or two AB sections still
remaining in the Harringay/Holloway area.
