Looks like this train, plus two others are still going strong at the Portland Zoo.
Portland’s Zoo Railway
HAPPY tots and smiling adults ride around the new $3,859,000 Portland, Ore., zoo on America’s latest railway—the Portland Zoo Railroad Co. The rocket-styled, Diesel-powered Zooliner hauls three gleaming Skydome coaches and a luxurious club car which tote 99 adults or 132 kids. The pike is headed by famed Pacific Northwest author and historian, Stewart H. Holbrook, Chairman of the Board, and John H. Jones, President. All aboard!

Pioneer Inventor Is Conducting a Radio Movie Station
DR. C. FRANCIS JENKINS, noted Washington scientist and pioneer in the field of radio vision, is now conducting a new high powered transmitting station near Washington, for the broadcasting of motion pictures by radio. Opening of his station was preceded by broadcasts from his laboratory for several months. The station was originally assigned to operate on a frequency of 2850 kilocycles with a power of 1.5 kilowatts. Dr. Jenkins has developed an instrument which changes the lights and shadows of the motion picture film into electrical impulses which operate the radio transmitter. The broadcasting equipment which is decidedly intricate includes a photo electric cell and a series of lenses for focussing.
