There appear to be 2 secret lines in South London that are about 1
mile to the east & west of the Northern Line, with trains running at
several
hundred miles an hour between approx Kingsway and Merton. Can anyone
tell me how I can get a ride, because I am sure it would be very
exciting?

I saw that too. Driven by Gremlins, perhaps.

If you click on the errant trains you get strange messages, such as

"District train to Upminster [024]
(left Stamford Brook Station,
expected Kew Gardens Station in 1.5 minutes)"
