I hadn't realised that the extension south to Staples Corner was built as
late as 1977. Whereabouts was the bit further south that was never built?

It would have continued to parallel the railway for another couple of
miles south (roughly to West Hampstead) where it would have joined the
infamous North Cross Route:

Blimey - a sort of inner-London M25! I'd no idea that there were ever plans
for this! It would have made life hell for all the people who live near the
route, wouldn't it? At least the M25 mostly avoids populated areas.
