Meet the Boeings: How Futuristic Visions in Postwar America Helped Bring Light Rail to San Francisco

Thursday, March 23, 2017

In the era of prosperity after World War II, Americans envisioned a future where space-age technology would bring greater ease and comfort to everyday life. People would have robot pets, live in bubble houses and ride mass transit via silent and speedy monorails. San Francisco took its first steps towards that vision in the 1960s with the construction of the Muni Metro / Bay Area Rapid Transit (BART) project to replace outdated streetcars with sleek trains that zip across town through the Market Street Subway.


Moving from streetcars to modern light rail vehicles (LRVs) was a trend among similar cities at the time. But Muni needed a special kind of vehicle that could serve both low-level platforms at its pre-existing stops on surface streets and high-level platforms in the new subway stations.

With few rail transit vehicle manufacturers to choose from in the 1970s, San Francisco and Boston turned to the Boeing-Vertol company, primarily an aerospace manufacturer, to build an LRV that could serve the atypical needs of both cities’ rail systems. Unfortunately, the design compromises made to meet that goal resulted in the Boeing LRVs suffering from continual mechanical problems. 


After only 18 years (half of the typical fleet lifespan of more than 30 years), Muni began to replace the Boeing trains and introduced the silver and red LRVs, manufactured by AnsaldoBreda, that Muni riders know today.

A new era of modern rail transit for Muni starts this year as the first new, state-of-the-art LRVs from Siemens arrive to supplement and ultimately replace the aging Breda cars. This fleet of the not-so-distant-future will run more quietly, efficiently and reliably than any of its predecessors. The trains are expected to go an average of 59,000 miles without major maintenance, more ten times longer than the current trains.

While the future of effortlessly gliding monorails envisioned in the mid-20th century may have never come to pass, Muni continues to move towards a future with a safer, more reliable transit system for the citizens of San Francisco.
