The motors of the San Francisco cable car system can be seen in the cable car museum. Each cable here controls one of the four lines which are now in operation. The cables move around through trenches underneath the streets, and the cable cars grip on to the cables to move.
This is one of the most famous postcard views of San Francisco: the houses are even often informally dubbed ‘Postcard Row’. The ‘Painted Ladies’—Victorian houses along Alamo Square which were mercifully spared by the Great Earthquake of 1906—are seen in front of the modern buildings of downtown San Francisco, including the Transamerica Pyramid.
