Yes, Northfields and South Ealing are the stations,
on the Piccadilly Line. They are only 0.48km apart.

Is that the distance between the station buildings? The platforms
run towards each other, so the nearest ends of the platforms must
be only about 240 metres apart.

It's the distance quoted in CULG, and is probably an official LUL
distance, but I can find nothing on the site which indicates where such
distances are measured from.

The middle of the platforms is the only thing that would make sense.

If the far ends are 600m apart (underneath the roads they cross), and
the near ends are 250m apart; then that would be 425m, which is close
enough (given errors in the other two estimates).

My earlier figure of 850 feet or 259 meters between platform ends comes from
an LT signalling diagram.

So the other way to do the sums is to guess the platforms are 170m long
(room for 10 cars), which makes the middles 429m apart (and the ends
599m apart, which is exactly where the roads are).

480m doesn't fit that quite so well, unless the platforms are actually
even longer than that. Maybe someone can let us know if the platforms
extend under the roads at all.

Northfields 425ft = 129m
South Ealing 427ft = 130m
Gap 878ft = 268m
C2C 1255ft = 383m

Total length including both platforms = 527m
Gap + half of each platform = 398m

C2C = from most central point marked on each platform
