The reasonably practical measure taken at Old Dalby is presumably not
having staff walking at track level without an isolation.

Looking at e.g. https://www.youtube.com/watch?v=S9k7XvFH3pE there
isn't a lot of DC track out in the open away from the fenced off
"depot" and there is about 200y of shielding at the far end of the DC
track (about 5:12) which is rather more than usually seen at
transition points.


We will have to disagree about what “isn’t a lot is “ .

Quoting from this website.

http://www.old-dalby.com/operation.htm

“This line is now electrified with 750v DC conductor rails for
approximately 3 miles and the SSL trains are based in the compound during
the daily testing. The yard sidings at the former control centre have also
been equipped. Power for the DC line is routed from the sub-station at
Asfordby. All other functions are now conducted from the new complex at
Asfordby, and the SSL trains travel to and from Asfordby each day, hauled
by a diesel locomotive.”

The DC electrification seems to be a minor proportion of the length of
track travelled in the video. The video is dated 2011 so it is
possible some more has been added since.


There are more up to date ones which would have been a better choice such
as this one from the cab of an S stock train under test.
