      Regen is just an electric car thing though, no? And EVs (with very few exceptions) don’t have a transmission at all?

          True but again, most modern trains don’t have the internal combustion engine directly delivering power to the wheels, they’re hybrids where the engine is essentially just a generator powering an electric drivetrain. You can’t have regen without a place to put that regenerated electricity, engine braking is distinct as that energy goes toward compressing air in the cylinders and generating heat that just goes out the exhaust as waste.
