On a more general note, how can one go about getting accurate
information about the routes of underground railways? Are there some
sort of official maps somewhere?

There is the map at the end of ...

http://www.londontransport.co.uk/tfl.../marketone.pdf

... it is not wonderfully detailed, but it does show that crossing
point south of Green Lanes.

But is that just luck? The map is wrong in other areas, for example the
Jubilee Line between Baker Street and Bond Street, or DLR at Bank.

I haven't yet found a fully accurate map.

But how do you know whether a map is accurate? That you can evaluate them
implies that you have some sort of authoritative source of knowledge about
the routes - which is what i'm after!
