From what I've heard:

Jubilee line extends from Charing X to Aldwich, including a lengthy reversal
siding.

(Technically, I'm not sure you can consider this overrun now as the Charing
X branch is closed anyway, so in effect it's an unused branch comprising
partly disused and partly unopened track).

Victoria Line South of Brixon negotiates a fairly tight curve as far as the
Upper Tulse Hill area where (in some proposals) a Station would've been
sited on the abortive Streatham extension.

Bakerloo Line beyond Elephant has one tunnel only that goes most of the way
to Camberwell.

At the north end of the Vic, it goes a fair distance towards walthamstow
wood st.

Do trains ever run down these tunnels or are they just for emergencies only
or derelict? Does anyone know if they have special exits to the street at the
end, since if a train did run down there and be stabled how would the driver
get out , would he have to walk down the track back to the terminus station?
