Thanks very much, Martin. Unfortunately, the route shown is not quite
accurate as it shows (eastbound) a left turn out of South Ken station, then
a straight section, then another left turn and a right turn by Brompton
Oratory. Anyone who travels that line will know that the bends go
left-right-left-right with no straight section before the old Brompton Road
station.

Just about all of my Bartholomew and Bacon maps going back to the early
years of the 20th century show this straight section - unfortunately,
hard-to-check details such as this were often copied by generations of
map-makers and thus errors were perpetuated.

Your map looks like an updated version of my Bartholomew street atlas of
1956, which shows the same route. I was hoping to find a more accurate one!

The best I can come up with is shown at
http://www.musonix.demon.co.uk/temp/southken.JPG

This is scanned from a 1940's A-to-Z and shows the first bend (going
east) in a more serpentine fashion - the second bend is not marked but
clearly follows the line of the Brompton Road.

Its not greatly different to Martin's map - in both cases the angle of
the Piccadilly's arrival at South Ken (from the east) is distorted by
the map-maker's wish to show it separately from the District by crossing
the latter and sending it too far south.

I suspect that a tube of this age would have stayed under streets (in
this case South Terrace) as far as possible before turning sharp north
(under private property for a short distance) and then continuing under
the curve of the Brompton Road.
