1 Jan 1871 Jahr - First elevated railroad begins operation in New York

Beschreibung:

ew technologies helped residents and visitors negotiate the industrial city. Steam-driven cable cars appeared in the 1870s. By 1887, engineer Frank Sprague designed an electric trolley system for Richmond, Virginia. A central generating plant fed electricity to trolleys through overhead power lines, which each trolley touched with a pole mounted on its roof. Trolleys soon became the primary mode of transportation in most American cities. Congestion and frequent accidents, however, led to demands that trolley lines be moved off streets. The “el” or elevated railroad, which began operation as early as 1871 in New York City, became a safer alternative. Other urban planners built down, not up. Boston opened a short underground line in 1897; by 1904, a subway running the length of Manhattan demonstrated the full potential of high-speed underground trains.
