Street railways arrived early in Portland and made lasting social and
economic contributions that are still apparent in the layout and
character of the city's neighborhoods today. During the 1890s, streetcar
lines spread rapidly into the West Hills and across the Willamette
River. The technological prowess of the growing Rose City was reflected
in the largest horsecar in the Northwest, the second steepest cable car
grade in the nation, the first true interurban railway, and an annual
illuminated trolley parade. By the dawn of the 20th century, Portland
could boast of the largest electric railway system in the West, as well
as its first eight-wheeled streetcar. The streetcars lasted into the
late 1950s here, and then, after a hiatus of nearly 30 years, were
rediscovered by a new generation of urban planners.
