The third embodiment175 years of history

Horse- or mule-drawn streetcars supplanted road-going omnibuses in the 19th century, eventually covering wide swaths of the city. In 1893 streetcars began the switch from animal to electric power. The new cars were hailed as faster and more comfortable, and soon residents were going out of their way to ride on them, reportedly walking past lines that still used animals.

Labor disruptions were common in the 1920s. Violence broke out in 1929 amid a strike by streetcar workers. An angry pro-union mob overturned the first car operated by strike-breakers. A streetcar barn was blown up and five streetcars were burned before the strike ended in October. Ridership plunged.

Streetcars remained the dominant mode of transportation around New Orleans in the 1930s, but their golden era had passed.
