Key System 308

A loyal Twin Coach customer, East Bay Motor Coach Lines (Key System) acquired 11 (#301-311) model 15 “baby” Twins in 1932. Seating just 17 passengers and about the size of today’s full size passenger vans, the small Twins were used on lightly patronized lines feeding Key System’s streetcar network in the 1930s. The #308 survived into the post WWII era having been made into a work car by Key System when John J. “Jerry” Graham acquired it in the late 1950’s. It, along with several other vintage buses and trucks, were stored on his property in Atherton, CA for many years.

The PBM acquired the #308 from the estate of the late Jerry Graham in 1996. This venerable bus shares its regional transit heritage with former Key System Twin Coach #400 as being the oldest coaches in the Pacific Bus Museum fleet.
