_Really_?

Greenford East is the closest mainline* mechanical signalling
installation to Charing Cross; once it's gone, there won't be any
mainline mechanical signalling anywhere near London.

Would the signalling in the area be controlled locally, or would it
be connected to Slough New or Marylebone?

Apparently, it will be covered by Slough New, when the Heathrow branch is
taken over from Slough New by a new panel at Heathrow, presumably as part
of the T5 works.
