#3270 – San Francisco Municipal Railway (Muni)

Initial Service

The PBM’s Muni #3270 was part of a fleet of third-generation 40-foot “New Look” GM buses delivered between 1969 and 1971. All but ten were T8H-5305’s (#3000-3179 and #3190-3389). The gap was filled by ten air-conditioned T8H-5305A’s (#3180-3189). In total, only 212 of those were built.

“It is seen here atop Twin Peaks in San Francisco in this July 1993 photo. Like all the buses in this series (3000-3390) #3270 is powered by a GM 8V-71 diesel engine coupled to a three speed VS2 transmission. To deal with San Francisco’s steep grades General Motors modified the transmission end shaft which reduced speeds in all three gears and gave the coaches sufficient hill climbing ability. For descending grades they were equipped with “Jake Brakes.” #3270 is featured in the adopt a- bus program…(photo, Bruce Maher collection)” – Source PBM Member Newsletter, The Paddle, Jan/Feb 1998
