- General Electric Company Catalog, "Electric Mine Locomotives," 1904 - At the turn of the 20th century, General Electric manufactured several models of electric locomotives for use in underground mines -- where smoke and soot from steam locomotives was dangerous and impractical. These small mine locomotives collected electricity from overhead lines or third rails that ran alongside the track. GE also built larger electric locomotives for use with conventional railcars aboveground.

- General Electric Thomson Recording Wattmeter, circa 1903 - Elihu Thomson, engineer, inventor and cofounder of the Thomson-Houston Electric Company, developed a commutator-type wattmeter in the late 1880s. His recording watt-hour meter helped transform the nascent electric power industry. The sturdy device provided companies that supplied electricity to consumers a way to accurately track and bill electrical power use.

- Edison General Electric Company Ammeter, 1889-1892 - In the late 1800s and early 1900s, companies that supplied electricity to consumers needed a variety of instruments to regulate and monitor electrical output. These instruments were vital to the operation of power stations and needed to be accurate and rugged. Ammeters--used to measure the current in a circuit--could be found on switchboards or connected to motors and generators.

- American Locomotive Company Steam Locomotive, 1902 - The American Locomotive Company of Schenectady, New York, built this locomotive in 1902. It is a 4-4-2 Atlantic type, with four leading wheels, four driving wheels, and two trailing wheels. The Atlantic was designed to pull light wooden passenger cars at high speeds. This locomotive operated on the Michigan Central Railroad's Detroit-Chicago line until heavier steel cars made it obsolete.

- General Electric Edison Number 6 Rheostat, circa 1892 - Rheostats vary the amount of electrical resistance in a circuit. They proved beneficial as the use of electrical power expanded in the late 1800s. Among their many applications, rheostats helped motors start safely, controlled motor speed, maintained a constant current in battery chargers, and adjusted volume and light levels.
