door width to train door width).

IIRC the Jubilee Line has now switched over to an automatic system.
It was conventional for a long time despite the original intention
that it should be automatic.

OTOH it utilizes different technology than the Victoria Line.

is that still the case? *My understanding is that a new system has been

According to Modern Railways 2011-07 page 71, the Victoria Line
utilizes DTG-R (Distance to Go Radio). *The Jubilee Line, OTOH,
utilizes Seltrac S40 from Thales.

To be pedantic, ATO (Automatic Train Operation) is just one element of
an ATC (automatic train control) system. Which comprises ATP
(Automatic Train Protection), ATO and ATS (Automatic Train
Supervision) all of which are different between Vic Line and Jubilee
Line (and in fact the Central Line).
