QDo you know any official London Underground map that shows the Metropolitan Line/stations beyond Aylesbury (i.e. the Brill and Verney Junction branches) and not just mentions them in a ‘To’ box?

ANo, I haven’t ever seen a map with “Underground” branding that shows the entire network and the Metropolitan Railway’s fullest extent out to the far reaches of Brill and Verney Junction, some 40-odd miles from London. 

The closest I can find is a Metropolitan Railway map (first image above) that was produced in slightly different versions from the mid-1920s up to 1933, after which all the railways merged to become the London Passenger Transport Board, the precursor to today’s Transport for London. This map shows the Metropolitan Railway’s routes in red and all the other “tube and district railways” in blue, so it does show the whole network, but not in a very equitable way!

The other map that I know of that includes Brill and Verney Junction is the famed “Metro-Land” map (second image), but it only shows Metropolitan Railway lines, and only as far east as Baker Street.

There’s no Harry Beck tube map that shows these branches, either: the 1932 proofing map only goes out as far as Rickmansworth, and any “To:” boxes he later added to the Metropolitan Line only ever went to Aylesbury. The Brill tramway closed in 1935, with Verney Junction’s branch following in 1936, so there wasn’t that much cross-over with the “Beck and beyond” design period.
