Electric trolley cars or trams were once the chief mode of public transportation in the United States. Though they required tracks and electric cables to run, these trolley cars were clean and comfortable. In 1922, auto manufacturer General Motors created a special unit to replace electric trolleys with cars, trucks, and buses. Over the next decade, they lobbied for laws and regulations that made operating trams more difficult and less profitable. In 1936 General Motors created several front companies to purchase and dismantle the trolley car system. They received big investments from Firestone Tire, Standard Oil of California, Phillips Petroleum, and others in the automotive industry. Some people suspect that these parties wanted to replace trolley cars with buses to make public transportation less desirable. This would then increase automobile sales. The decline of the tram system in North America could be blamed on many things—labor strikes, the Great Depression, regulations that were unfavorable to operators.
