volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force.[1][2] It is named in honor of the Italian physicist Alessandro Volta (1745-1827), who invented the voltaic pile, the first modern chemical battery.

Volt
A unit of electrical measurement which determines the level of force or pressure behind an electrical current. The greater the voltage, the more powerful the current.
The 5-volt supply has two outputs called "+5" and "signal ground". The "signal ground" is the common return for the electronics on detectors and signal control circuits.
Each 14-volt lamp (large) - 3
Each 18-volt lamp - 5
* These wattages are drawn by locomotives when pulling the regular number of cars and include the power used by the whistle. However, you must add the wattage used by lamps in illuminated cars.

Alternating Current (AC) - Standard 110 Volt house hold current, or low voltage current used in model railroading, usually around 18 Volts; An electric current that reverses its direction of flow at regular intervals.
The South Shore employs a 1500 volt DC overhead electrical system to power their passenger trains. Much of this overhead trolley system dates back to the days of Insull ownership as well and in recent years has become prone to failure.
Both Atlas and Walthers use permanent magnet 12 volt motors to power their turntables. If perchance, you have an ancient or exotic turntable with a series field motor (see Figure A) it probably runs on 12 volts or less.
The pack that comes with a starter train set (rated as low as 7 volt-amps, or just 0.7 amps delivered at 10 volts) will run one (maybe two) locomotives at the same time. A 14 VA pack will easily power three or four locomotives.
Use a 9-volt battery at first to test-position them in the yard to determine where they enhance the scene most effectively. Then drill the hole(s) to the bottom of the layout. Thread the wires to the bottom.
[MR] A unit that changes 110 volt house current into low voltage current used to run the trains and accessories. Sometimes called transformer.
