Opposed-piston 2 stroke diesel engines were once the design of choice for submarines where HP per cubic foot was all important and cost was of little concern. Similar engines, and even more unique designs were used by others for other applications nearly always in confined space and or very low weight applications. For further interesting reading, google Napier delta design ship engines.
Fairbanks-Morse attempted to market the opposed-piston design engines for railroad locomotives where they failed miserably due to reliably and serviceability issues.
FWIW, the GM 2 stroke diesel engine design was built for far longer than 57 years. Google Winton Diesel. Winton pioneered the two-stroke diesel engines for railroad use in the late 1920s/early 1930s.

I believe but did not verify that the EMD 710 series engines are still being built for railroad applications. If not, they were quite recently.
