When Muni light rail underwent its
major transformation in the late 1970s and early 1980s, the
then-existing fleet of
PCC trolley cars gave way to the kind of vehicle pictured in this scene. These LRVs were briefly and rather unsuccessfully
manufactured by Boeing-Vertol, with similar units furnished both
to San Francisco and Boston. After a couple decades or so of service all
San Francisco units were retired. Boston saw its last units in regular
service in 2007.
This run is about to negotiate the tight
loop at Ocean Beach.
