I wonder if they employ trippers on that stretch or if they fit the

I've seen the tube trains under test at Old Dalby (last time I drove up
to the East Midlands a month ago). Unfortunately there wasn't anywhere
convenient for me to stop to take a photo.

The other odd thing about the line is the OHL a long way from any
electrified service lines. https://goo.gl/maps/Q70Uo

I think it's the only section of track, anywhere, with both fourth rail and
overhead electrification. I think that it's currently being used for both S
stock and IEP testing. Old Dalby is also where the currently surplus S7
stick waiting to enter service is being stored.

One unusual location for ex-LU stock the BBC missed is Long Marston:

IIRC Drayton Park has both fourth rail and overhead,
although obviously not for much distance.

The fourth rail might not be doing a lot unless it has been left
connected but dropped onto the sleepers as done between Harrow and
Watford.

It's certainly not a functional fourth rail, and nor would 313s connect to
a centre rail anyway.
