      The solenoids inside the turnouts don't care if the voltage is AC or DC. The
      most commonly used power source is the AC accessory power on a power pack,
      nominally 14-18 volts. They also work fine on 25-28 volts from capacitor
      discharge circuits as well. Obviously, voltage is not a critical issue.

      The key is *how long* you apply power, no matter the power source. Anything
      over a very short fraction of a second of applied power puts the turnout at
      risk of being burned up from heat in the solenoid coil. While this is true
      in all scales, it is more important in Z scale given the ultra small wire
      that the solenoids are made with.
