Are there/were there? Any plans to extend the Central Line past West
Ruislip?

The original (pre-war) plan was to continue two stations further -
Harefield Road and Denham. Post-war greenbelt legislation restricted
housing development, and thus potential passengers, in the area, so this
final part of the westward extension was never built.

I have a street atlas* with a map that shows it as existing. Denham is
there, but no station at Harefield Road.
