When the Pacific Electric Red Car line was torn out in Los Angeles, a man named Smith bought about eight of the old trolleys and brought them up to a large parcel that he owned in the northern San Fernando Valley.

He strung them together with short corridors between each car, using one as a kitchen, one as a family room, several as bedrooms etc. He and his wife raised a family there. When he retired, or died, in the 70s, the property was sold and the streetcars were demolished.
