Not "clutch".
There were "diesel-hydraulic" locos in Britain.
"Hymek" and "Warship Class" (???).
Were they British "licences" of German designs?
Seems a very German example of precision engineering - not easily
replicated elsewhere.
Advantage is said to be that hydraulic-mechanical transmission weighed
less than electric transmission, so could pack more punch if the loco
had to be small and light due to track / axle-load, etc.
Check the real facts if interested.
Used primarily on narrow guage??
Mainline - Standard gauge - Western region of UK. Hilly routes.

Be a royal bitch if it sprung an oil leak!!!
They were also "multi speed" geared transmissions - running on the
short lines in the UK I guess they stood up OK,but I doubt they would
have lasted long on our transcontinrntals and hauling freight through
the North American Rockies, or even the appalachians with trains
several miles long.
