Chicago's extensive transit system first started in 1859, when horsecars ran on rails in city streets. Cable cars and electric streetcars came next. Where new trolley car lines were built, people, businesses, and neighborhoods followed. Chicago quickly became a world-class city. At its peak, Chicago had over 3,000 streetcars and 1,000 miles of track--the largest such system in the world. By the 1930s, there were also streamlined trolleys and trolley buses on rubber tires. Some parts of Chicago's famous "L" system also used trolley wire instead of a third rail. Trolley cars once took people from the Loop to such faraway places as Aurora, Elgin, Milwaukee, and South Bend. A few still run today.

When it came to first-class transportation, not many regions of North America had more to offer than the trolley lines of New Yorks Capital District. From their humble beginnings as horse roads forming belts around Albany, Schenectady, and Troy, these trolley lines helped move people around Upstate New York from the late 1800s until their final exit after World War II. The lines of the United Traction Company, Schenectady Railway, and the Hudson Valley Railway provided hundreds of miles of track around their home cities, as well as direct routes to resorts in the Adirondacks, Lake George, and Saratoga Springs. The trolley lines became famous for disasters that made national headlines, labor disputes, and engineering wonders that included the longest trolley bridge in the world. The vintage images in Trolleys of the Capital District provide insight into an era gone by and an often forgotten form of transportation.
