Car 1218 was built in 1929 by the Key System Transit Lines in their Emeryville, Ca. shops. It was rebuilt from a freight motor flat of the same number. The car was equipped with stake pockets external the side sill. The car was used to build the Shipyard Railway, as car 1201 was too wide. The stake pockets were removed at this time to give 1218 clearance to get by the high level platforms used on the Shipyard Railway in Emeryville and at the shipyards in Richmond.
