I would have thought not, TBH, as I understand that there are legal
limits as to the length of freight here trains in England, and much of
Europe.

I have seen images them in the United States, Russia and Australia
however. The Russians and Australians seem to have them to haul iron ore
and various coal grades.

I believe the limits are not legal but technical (length of sidings).
The new European standard is an upgrade to 740m on main freight routes,
with some special routes allowing for longer 835m trains.

DPU becomes a necessity when the train weight exceeds the strength of
the couplings. Europe is prototyping automatic "Schaku" couplings, with
the aim of modernizing the wagon park completely within the next 10-20
years, reducing the need for DPU as opposed to multiple power units at
the front of the train (thanks to largely powerful Electric traction,
the need of multiple units in Europe is reduced compared to Diesl-only
countries).

AIUI, the 700m iron ore trains in Lulea are now pulled by a single
electric unit, using the stronger Russian-style couplings.

Semi-automatic knuckle couplers, I believe.

Signalling section limits not legal limits. The up-to roughly half a
mile long High Output Ballast Cleaner train requires special
arrangements when travelling to/from work sites because of its length.
