A trolley car (or streetcar) is similar to a railroad passenger car. Like a train, a streetcar runs on a set of rails. Streetcar tracks are usually in or alongside city streets. An electric streetcar is sometimes referred to as a “trolley”, because it has a special pole that extends from the roof of the car to an electrified overhead wire, similar to a telephone or utility cable. The trolley pole collects power from this overhead cable and sends it to the motors located underneath the streetcar. The operator “drives” the streetcar with a controller. All of our currently operating streetcars can be operated from both ends and, with the exception of car 122, have two trolley poles. When the operator switches the pole, he or she is, in effect, “changing ends,” instead of having to physically turn the car around to go in the opposite direction.
The first streetcars, pulled by horses or mules appeared in 1828. By 1886, 300 US cities had horse car lines. In 1876 some streetcar lines were powered by little steam “dummy engines” disguised to keep from scaring horses. Seeking a more economical way to power streetcars, Andrew F. Hallidie developed cable cars. Although cable cars were first used in San Francisco, they ran in 27 other US cities as well.

Leo Daft’s early streetcars picked up power from two overhead lines on which rode grooved wheeled trollers which had a bad habit of frequently dropping off the wires. This method never achieved any satisfactory degree of reliability. However, the word “troller” evolved into the word “trolley.”
Charles Van Dopoele devised a practical spring-loaded trolley pole to collect current from a single overhead wire.

In 1888, Using the Van Dopoele method of current collection, Sprague opened his first streetcar system in Richmond, Virginia. The line’s success spawned similar street railways all across the world.

Although a streetcar running on electricity gets its power via a trolley pole from the overhead wire, a cable car is pulled along by a special cable located under the street in a slot between the rails. This cable runs continuously at 9 miles per hour. The cable car operator is called a “gripman,” because he controls a special “grip,” that grabs onto the cable to run the car, and lets go of the cable when he wants to stop the car.
Cable cars once operated in many cities around the world, but were replaced by more efficient, lower cost trolley cars. The only surviving cable cars are the famous ones of San Francisco that have been running for over 100 years
11选5买一注多少钱PCC streetcars were designed in the mid-1930s to defend the use of streetcar trolley transportation against increasing automobile competition. The (Electric Railway’s President’s Conference Committee) car, was an industry-wide consortium established to produce a standardized, streamlined, smooth, quiet, fast, comfortable and stylish cars. The first PCC car was tested in Brooklyn, NY, in 1936. Eventually 4,000 PCCs ran in 29 cities in North America.
Dallas received 25 double-ended PCCs in 1945. The transit company had planned to order more, but instead decided that the future of public transit was the electric trolley bus. After streetcar service ended here in 1956, Dallas sold their PCCs to Boston where they ran for 3 or more decades. The M-Line has acquired one of these to restore.
In 1996 MATA purchased 2 PCCs in almost brand-new condition from the Toronto Transit Commission. In 2012, MATA began readying one service.
Dallas had outgrown its remaining four streetcar lines and there was a lot of pressure to to replace them with buses.
11选5买一注多少钱Most of Big D’s streetcars were 30 years old or more. They interfered with a planned one-way downtown street system. The merchants on Jefferson Avenue in Oak Cliff wanted the trolley tracks removed from the center of the street so they could add more parking spaces. The locally owned transit company had been sold to an outside pro-bus firm. The mayor believed that Dallas could never become a modern city while it was “tied to an antiquated electric rail transit system.” America’s postwar love affair with the automobile had helped to diminish the popularity of mass transportation.
The M-Line’s operating expenses are provided through a Shuttle-Agreement with Dallas Area Rapid Transit, as well as yearly donations from the Uptown and Downtown Public Improvement Districts. Other income comes from advertising on the trolleys, endowments, individual donations from the public, and membership fees. We also rent out our trolleys as special charters for children’s birthday parties, dinner parties, company parties and private parties.
