Key System 400

Similar to the PBM’s East Bay Motor Coach Lines (Key System) #308 this larger 1933 Twin Coach model 30 was the only one of this model to be operated by the East Bay Motor Coach Lines. It was kept around long after its passenger carrying days as a Key System service coach.

Acquired by John (Jerry) Graham in the1950s, it along with several other vintage buses and trucks were stored on his property in Atherton, CA for many years.

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