Here's one I made earlier...https://www.independent.co.uk/travel/news-and-advice/batteries-included-east-anglia-leading-a-railway-revolution-with-self-charging-train-9984034.html

But it wasn't quite what I was looking for.

Ah, here it is:
"the Class 419 battery motor luggage vans were capable of running on batteries or a third rail, useful for short non-electrified sections on quayside lines at Folkestone and Dover."
https://en.wikipedia.org/wiki/British_Rail_Class_419

I thought there was once also a passenger set for a short branch somewhere in third-rail territory, but that's only a vague memory and could be wrong.
Ran down from London on 3rd rail, but did it's own little thing at the end?

Were you thinking of this one https://www.railcar.co.uk/type/battery-multiple-unit/, although this is far, far, away form third rail territory. It still exists at it's original area of operation. 21st century technology - 1950s style!

From 2017 in the UK! I'm sure it's been done elsewhere as well... There's also the Vivarail 230.

The BEMU was a Derby Lightweight two car set equipped with batteries and a EMU motors. It was converted on the production line, so guess its age. It ran on the Aberdeen to Ballater line, was then withdrawn and used for AFAIK engineering works, and finally taken on by the Deeside railway. At the time they took it over the original batteries still had some life left in them, having at some time been chemically rejuvenated. The Batteries are now life expired and the stock is being used loco hauled awaiting funds for battery replacement. AS the original batteries were funded by Scottish Hydro for publicity Lending them saome modern battery packs would be good publicity for a current manufacturer.
Even earlier (1932) were the Drumm battery electric units used in Eire. There were two 2car articulated units.

They looked a sight better than Southern MU stock of the time.

"The train includes four traction batteries and can travel around 40 kilometers, roughly 25 miles!

Now that's what I call a "stay-alive" unit!. :o :lol:

Trouble is a lot of their non-electrified branches are longer! :)

I think they had thought about that, as although there wasn't to my knowledge any electrified lines for them to run on, current collection was by pantograph, according to Wikipedia. I can't see any point to fitting a pantograph unless you want to draw current on the move. So was there some thought of putting up charging sections. If there was there's nothing new under the Sun, as that is precisely what is being proposed for various tram systems and some East Anglian routes.

Many of the branches they have finish in a station which is on a mainline and is electrified. So the idea is probably for them to charge during the turnaround time.

I know they are electrified now, but this was 1932, I don't think Eire had any electrified lines then. DART seems to have been their first electrification on heavy rail.

I think we are at cross purposes, John, I was referring to the OP's German units! ;)

Yep we weave a tangled web. Apparently electrics on the East Coast have been free wheeling through some extended dead sections, ok I suppose until you have to stop in an emergency,
I've seen footage of an Aussie electric going through a series of breaks in the overhead with the pan up, not just no power, no wires. Their bridge bashing record is so bad they won't risk letting drivers cross below wires.
