I was going to mention how hydraulic systems in autos are being replaced with electric. My Prius has no belt-driven accessories (or belt). Electric brake booster, electric power steering, electric AC...

Hydraulic systems are expensive and need frequent maintenance, and they aren't as efficient as a directly driven system. Trains use electric motors and have extreme torque/power requirements over a range of speeds. It seems many other things traditionally moved by hydraulic systems could be electrified. Not only would it be more efficient, but it might be cheaper in the long run due to eliminating maintenance of hydraulic systems.
