As a natural result of its profit-making possibilities, the gas-electric car for branch line and local main line service continues to show an increased use. Among the more important additions to existing equipment are sixteen cars to be placed in service by the Chicago, Burlington page 43 and Quiney Railroad, one single unit and two double power plant equipments by the Mobile and Ohio Railroad, ten single-unit power plants by the Seaboard Air Line, and three dual power plant cars by the New York Central Railroad. The Chicago, Milwaukee and St. Paul Railway is supplementing its fleet or gas-electric cars with ten of 275 h.p.
A single unit power plant car was shipped to the Victorian Railways of Australia for trial on the State lines around Melbourne. Another shipment includes eight cars for the United Railroad of Havana. In all, about 60 of these cars were placed in service during the year.
