Streetcars in North America Streetcars in North America Electric streetcars or trolley(car)s (North American English for the European word "tram") were once the chief mode of public transit in hundreds of North American cities and towns. Most of the original urban streetcar systems were either dismantled in the mid-20th century or converted to other modes of operation, such as light rail. Today, only Toronto still operates a streetcar network essentially unchanged in layout and mode of operation. Older surviving lines and systems in Boston, Cleveland, Mexico City, Newark, Philadelphia, Pittsburgh, and San Francisco were often infrastructure-heavy systems with tunnels, dedicated right-of-way, and long travel
North America The islands of the West Indies delineate a submerged former land bridge, which had connected North and South America via what are now Florida and Venezuela. There are numerous islands off the continent's coasts; principally, the Arctic Archipelago, the Bahamas, Turks & Caicos, the Greater and Lesser Antilles, the Aleutian Islands (some of which are in the Eastern Hemisphere proper), the Alexander Archipelago, the many thousand islands of the British Columbia Coast, and Newfoundland. Greenland, a self-governing Danish island, and the world's largest, is on the same tectonic plate (the North American Plate) and is part of North America geographically.
