AC motors are constant speed devices but their speed can vary if you change the input voltage or frequency or the windings that make the motor rotate.
AC
An alternating current (AC) is an electrical current whose magnitude and direction vary cyclically, as opposed to direct current, whose direction remains constant.
AC (Alternating Current)
Electric current which repeatedly alternates (Cycles) from positive to negative a specified number of times per second (usually 60 in the U.S.).
AC : Alternating current. Electric current which changes polarity in a regular cycle. It is the normal mains supply.
Current-AC--Alternating Current. Most AF locomotives operate on alternating current but, with universal motors, can run on DC (direct current) too.
AC, half-wave and full wave rectified signals
A rectifier is an electrical device that converts alternating current to direct current, a process known as rectification.
AC portions of an otherwise DC circuit may also use this symbol to indicate a common connection. the centre taps of power supply transformers for example.
AC&Y #66. The Akron, Canton & Youngstown was formally absorbed into the burgeoning N&W system in 1982, after having been leased in 1964.
AC electric motor whose speed varies in direct proportion to the frequency of the supply.

Connect the two AC terminals of your power supply to the input terminals of the 51750. Run a pair of wires from the first set of output terminals on the 51750 to the 12010 switch drive.
80-96 AC electric locomotives 80 to 96
97 Departmental locomotives (not in revenue-earning use)
98 Steam locomotives
99 Ships owned by British Rail (ferries, etc)
100-199 Diesel multiple units (DMU's) with mechanical or hydraulic transmission ...
Wiring can be done in series or parallel from an AC power source. If you wire them in series (connected end-to-end), the lamps have to divide the voltage, so that the bulb of each will be dimmer than it would be otherwise.
American Car & Foundry's (AC&F's) early steel cars were built at their Detroit plant, with one group of diagonal-truss hoppers going to the LS&MS in 1902.
- AC unit directly behind cab on the conductors side rear walkway
- Two dynamic brake grids, directly behind the cab (above AC unit)
- 2/3rds of panel area for air filter cabinet taken up by the intake grill (Vs.
The "trickle" power supply needs to be completely separate from the throttles (you cannot use one of the AC outputs on one of the throttles), a "plug in the wall" 12 volt AC transformer, such as a Radio Shack 273-1610A, works well.
Alternating Current (AC)
An electric current that reverses its direction of flow at regular intervals. Each move from zero to maximum strength and back to zero is half a cycle.
Motor Tool - A battery or AC powered hand-held motorized tool mounted with an interchangeable collet that can be fitted with drill bits, or other kinds of cutting, grinding, milling, and polishing tools.
...
Transformer: strictly speaking, an electrical device for raising or lowering AC voltage, but in toy train parlance, and AC power pack for controlling train speed and direction.
One thing that spices up night scenes is adding lights- street lamps, stop lights, crossing signals and billboards. Wire these all to a common bus, and then to the AC terminals on your powerpack.
Wiring Techniques ...
You'll notice that we're using the DC terminals. Some believe that the lights won't last as long with DC as with AC. What you can do to prolong the life is to switch the polarity from time to time using the reversing switch.
