These were replacements for Key System San Francisco-Oakland Bay Bridge Railway “Bridge Unit” trains.
The 547 model TDH-4801 buses that GM built from 1953 to 1958 were unique to California. The bus was designed in response to the California PUC complaint that the TDH 5105, as specified, would exceed the California axle load limit. Compliance was accomplished by shortening the wheelbase and cutting the rear overhang of the 5105.
KSTL was sold to the Alameda-Contra Costa Transit District (AC Transit) which started operation shortly after midnight on Saturday, October 1, 1960. #2103 was the first coach to go into service for AC Transit (owl service on the I route, driven by Guy R. Foster). AC Transit continued using the 2100’s on the bridge routes, but as the coaches became older they also saw service on local routes, including BART bus service routes and service in Fremont.
#2103 last saw service from July 1979 to February 1980 along with 2111 and 2115 as a training coach on loan to Santa Clara County Transit. She was retired upon her return to AC Transit in early 1980. She was restored in order to help celebrate AC Transit’s 20th anniversary in October 1990.
On a long-term loan to AC Transit by the Western Railway Museum, #2103 was donated to the PBM in April 2013.
The PBM is pleased to add this restored and operable GM “Old Look” to the museum’s bus collection.
This bus is popular at local events as a reminder of the beloved Key System and its San Francisco Oakland Bay Bridge “bridge unit” trains and their bus replacements.
