List of streetcar systems in the United States

This is an all-time list of streetcar (tram), interurban and light rail systems in the United States, by principal city (or cities) served, and separated by political division, with opening and closing dates. It includes all such systems, past and present; cities with currently operating systems, and those systems themselves, are indicated in bold and blue background colored rows. It is one in a group of lists that collectively cover all countries of the world; the other lists are indexed at List of town tramway systems.

This is not a list of streetcar operating companies. It is a list of U.S. cities that were the focus or base of a streetcar system at one time, with starting and ending dates for each general type of streetcar service (e.g. horsecar, electric streetcar) in each city or metropolitan area. "System", as used in the article title, refers collectively to all streetcar infrastructure and rolling stock in a given metropolitan area, used by any of several different operating companies over many years, often passing from one operating company to the next. The "Name of system" column is intended to distinguish the few cases where two distinctly different systems were in operation in one city at the same time, but is also used to identify operators that have a Wikipedia article. In many U.S. cities, the streetcar system was operated by a succession of different private companies during the years in which the system existed.

The use of the diamond (♦) symbol indicates where there were (or are) two or more independent streetcar (or light rail) systems operating concurrently within a single metropolitan area. Usually, this refers either to interurban lines connecting the area's principal city with other cities or to cases where separate cities within one metropolitan area were served by independently operated streetcar systems.

Unless otherwise noted in the "Type" column, all systems listed were/are conventional streetcar (tram) systems (although some past systems might have been termed light rail if that 1970s-introduced term had existed at the time they were in operation). Interurban and light rail systems are noted in that column for convenience.

Alabama

 * Peschkes (Part Four, 1998, page 26) states that a company was organized to build a steam tramway in Blountsville but never started construction, and that other sources tabulate this system among those in operation.

Colorado
Peschkes (Part Four, 1998, Page 59) states that, despite various evidence, the following town did not have a tramway:


 * Silver Cliff.

District of Columbia

 * Notes for Washington, D.C.:
 * Operation into Maryland, September 16, 1892 – January 2, 1960.
 * Operation into Virginia, 1923 – August 25, 1956.

Georgia
Peschkes (Part Four, 1998, Page 44) states that, despite the assumption of another historian, there is no evidence for tramways in the following towns:
 * Dahlonega
 * Dalton
 * LaGrange
 * Lexington
 * Summerville
 * Thomasville

Kansas

 * Peschkes (Part Four, 1998, Page 57) states that, although included in some statistics, the following (horse-drawn) streetcar systems were not built:
 * Beloit.
 * Dighton. Peschkes states that one source, dated 1888, states that this town had a streetcar line, but no confirmation was found.
 * El Dorado.
 * Marion. Peschkes states that "there is no more than a rumor" that this town had a horsecar line.

Kentucky

 * Peschkes (Part Four, 1998, Page 59) states that, despite various evidence, the following towns did not have streetcar systems:
 * Barbourville – Peschkes describes "a marvellous picture postcard of a horse tramcar in the main street of Barbourville, with a woman driver," dated 1917. Similar picture postcards exist for U.S. towns that did not have horsecar or streetcar systems.
 * Mount Sterling.

Missouri

 * Peschkes (Part Four, 1998, Page 80) states that, despite various evidence, the following towns did not have streetcar systems:
 * Excelsior Springs.
 * Lexington.

New Jersey

 * Note for Newark: The streetcar subway, the Newark City Subway, opened May 26, 1935. Also served East Orange and other neighboring towns. (See also Public Service Railway and Newark-Trenton Fast Line.) Last Newark streecar line not using the subway closed May 1, 1938. Last surface streetcar lines using the subway closed March 30, 1952. Since then, effectively operated as a "light rail" line; line extended in 2002. System expanded to include a second line in 2006.

New York

 * Note for Cortland – Homer – McGraw – Preble: Horse tramway connected Cortland and Homer. Electric tramway, opened April 1, 1895, connected Cortland, Homer and McGraw. Extended to Preble in 1907. McGraw Preble segment closed April 1, 1929. Remainder closed February 15, 1931.
 * Note for Newburgh – Orange Lake – Walden: Opened in stages, to Orange Lake in July 1894, completed June 1, 1895. Newburgh – Orange Lake operated during summer season, 1924 and 1925, petrol (gasoline) traction (?).
 * Note for New York – City Island: Experimental monorail operated Bartow railway station – north end of City Island bridge, July 15–19 1910, and November 14, 1910 – March 16, 1914.
 * Note for New York – Rockaway Park: Tramcars operated over electrified Long Island Rail Road tracks between Far Rockaway and Hammels, 1905 – September 9, 1926, using overhead current collection to 1912 and third-rail current collection thereafter.

Ohio

 * Note for Dayton: Town streetcar services were provided by a single undertaking in most U.S. towns. Such undertakings were often organized by consolidation ("unification") of predecessor undertakings. In most cases, such consolidations were completed before the First World War. Dayton was a notable exception. In this town, five undertakings operated town streetcar services from 1909 to 1933. Conversions to trolleybus began in 1933; remarkably, all five undertakings operated trolleybuses for several months in 1940, before the beginning of consolidations. See Trolleybuses in Dayton for further information.

Texas

 * Note: Peschkes (Part Four, 1998, Page 125) states that, although listed in some statistics, streetcar systems were not built in the following towns:
 * Brenham
 * Colorado City

 * Sulphur Springs
