If you click on a LUL/LOROL/DLR station, all three networks are displayed,
in line colours.

None of the lines seem to follow the tracks; they just join the
stations, often in a really bizarre way (like the Metropolitan cutting
through Regents Park).

I wonder if it's been done manually, because the treatment at various
places isn't consistent. Sometimes they "fit" a curve (eg Circle near
Farringdon and Barbican, where you can actually see from the photography
where the line should go) and sometimes there's just a sharp angle (eg
Circle at Tower Hill).

Some, (eg Angel) suffer from the station building not being above the
railway line. iirc the track runs under Pentonville and City roads.

Ealing Common to Ealing Broadway is the best example of track that most
"geographic" maps struggle with. And this one is no exception
