Let the climb halfway to the stars resume.

San Franciscos cable cars were back on the streets Monday, climbing hills and shuttling around tourists following a 10-day shutdown for much-needed repairs.

The three lines — Powell-Hyde, Powell-Mason and California — returned to service Monday morning after the repairs went as scheduled.

Beginning Sept. 13, workers began overhauling and refurbishing gearboxes that control the movements of the cable lines that pull the cable cars around the city streets. The old gearboxes housed at the Cable Car Barn on Mason Street had been in operation for 35 years.

The rehabilitation project began in 2017 and cost an estimated $6 million.

“The gearboxes have been in place since 1984, and their life expectancy was at an end,” San Francisco Municipal Transportation Agency spokeswoman Erica Kato told this publication through an email. “For the past two years we have been changing out the gearboxes, and the Hyde Line gearbox was the last to be installed. The gearbox that was removed will be rebuilt and kept as a spare.”
