London Tubes: Unexpected locations of underground trains
 

I wonder if they employ trippers on that stretch or if they fit the test
trains with AWS.

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 doubt they use either trips or AWS as it's a self-contained test
track. To get to and from they are dragged by a diesel loco.

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:

They mentioned the ex-Met Dreadnaughts on the Worth Valley, but not
the ex-Met Ashburies on the Bluebell.

Also found in the past at Shoeburyness.

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

The fourth rail isn't operational. It was disconnected when the overhead
was installed. It does have a short length of third rail and overhead, but
that's not uncommon.

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.

This seems to imply that overhead + 4th rail is in some way harder to do
than overhead + 3rd rail... I would have thought it would be the other
way around.
