Horse car and cable car systems in the Twin Cities spurred urban growth and gave residents more mobility. The coming of the electric streetcar in 1889 had an even greater impact. With cars that could travel faster and farther, the system grew to become one of the nation's finest public transportation networks before the dominance of automobiles and buses in the 1950s.
Before Minneapolis and St. Paul upgraded their street railway systems from plodding horse cars to modern electric trolleys, both cities flirted with the use of cable cars. Costly to build, only two lines operated in St. Paul before both cities converted to electric streetcar systems.
