  • 2. History in the making  Horse cars were the first form of public transit within cities.  The earliest horse car line was built in 1828 in Baltimore, Maryland.  Horses are slow and expensive as a form of power.  In larger cities horsecars were replaced by cable cars, or elevated steam trains.  Horsecar lines were prominent in cities until Frank J. Sprague’s invention of the overhead wire and motor mount in 1887.  The Sarah Street line in Pittsburgh, Pennsylvania, was the last regularly operated transit line operated with horse cars in the United States, running until October 27,1923.

  • 4. How Streetcars Work
  • 5. Early Streetcars Many people know streetcars as “Trolleys” popularized by the childrens’ TV show Mr. Roger’s Neighborhood; although the proper name is a “Streetcar” or “Electric streetcar” Early trolleys were not much different from their predecessors. They were small, with only 1 truck (wheel and axle set) and as such could not carry a large passenger load.
  • 6. Evolution of the Trolley City cars: Trolleys that ran within cities or towns. Streamliners: Modernized trolleys first seen in the late 1930s early 40s. Interurbans: Trolleys that ran between towns and cities.
  • 7. Evolution of the Trolley Light-rail: The newest generation of trolley transportation. A new Pittsburgh LRV (Light-rail Vehicle).
  • 8. Demise of the Trolley Era As automobiles became more popular and more available to the average American, trolley companies began a downward spiral. Trolleys were stacked and burned to strip the metal bare.
  • 9. What Once Was In the teens and twenties it was possible to ride trolleys from Pennsylvania to Illinois (with a lot of transfers in- between).
