San Diego Transit 517

San Diego Transit GM old look TDH4801 coach 517San Diego Transit Lines GM TDH4801 # 517 was as part of a 20 bus order (511-530) delivered new to San Diego Transit Lines in 1957. After its career with San Diego Transit 517 was sold to Yuma Bus Co. in Arizona and then to an individual living near Yuma where it sat for 18 years. It was then purchased by southern California bus collector, Andy Goddard, who moved 517 to the San Diego area where it was eventually bought by Chris Stauffer. The opportunity to acquire a complete and operable GM “Old Look” as a back up or reserve bus for the Niles train shuttle came in the fall of 2006 when the PBM acquired 517 from Chris in October 2006.
