    And I'm not terrably fond of hydraulic transmissions. They're not
    terrably reliable compared to manual mechanical transmissions. I
    won't own another car with a hydraulic transmission, if the slightest
    thing is wrong, the car becomes difficult to drive. Whereas if I'm
    controlling the clutch and gearshift myself, the vehicle becomes
    considerably more robust.

    Yup, they call it rheostatic braking. Basically, the juice just gets
    burned off by what amounts to giant oven coils under massive fans (the
    big fans you see on most American diesel-electrics). Portland's MAX
    uses a similar system of braking to send power back on to the line.
    My school used to share a (small) substation with the trains, you
    could tell when a train was slowing down on the line up the street
    because the lights would get slightly brighter, and if a particularly
    full train (and thus heavy, requiring full throttle to accellerate
    reasonably well) would make the lights slightly dimmer.
