In 1873, the first cable railway in the United States began operation in San Francisco. In subsequent years, the Clay Street Railroad was joined by many other operators throughout the U.S.A., including systems in New York and Los Angeles. The rise of the electric trolley made most cable car systems obsolete. Today, the only street cable car system in operation is the historic San Francisco Municipal Railway. Originally published in 1887, this prospectus was prepared by patent holders in hopes of attracting additional operators and investors. The document describes the cable car system and its operation in text, diagrams and photographs, and presents a detailed list of patents. This easy-to-read reprint is presented in format, sightly larger than the original. However, care has been taken to preserve the integrity of the text.
