A locomotive is followed through an engine terminal where it is refueled and serviced for its next trip. Use of the turntable and roundhouse, sand tower, oil and water penstocks, inspection and washing are shown. Sound backgrounds of steam locomotives are used to give feeling of reality THE STEAM LOCOMOTIVE. NYCen 1944 22min sd (Running the railroad) loan 621.13 Jh-sh-c-tr-ad "The Hudson type locomotive Is the chief subject of the film, and its construction, operation, maintenance and capabilities are clearly explained. "The action of the automatic stoker, air brakes, water scoop and other mechanisms Is shown in detail, and an animated sequence explains the principles of steam production and the manner In which the steam moves the engine. "Impressive scenes showing magnificent trains in action precede the scenes that depict service and repair in the roundhouse. "Exceptional shots taken In the cab of the locomotive and from moving trains adjacent to the engine conclude this . . . film." Movie makers 621.2 Hydraulic engineering BASIC HYDRAULICS.

It is shown how rapids and waterfalls, by this use, were changed from hindrances to aids to man's progress Traces the development of water power, chiefly in the United States, from the small mill of the early colonist to Niagara, Boulder dam and the Tennessee valley There is an informative sequence on the transformation of kinetic energy of the waterfalls Into potential energy thru the hydroelectric plant Concludes with a worldwide survey of potential water power in the main river systems of the continents 62 1 .3 Elecf ric engineering CARBON— BLACK TREASURE. 1946 37min sd color apply NatCarbon 621.3 sh-c-tr-ad Produced by Roland Reed "The manufacture of electrodes to deliver the thunderbolt electrical charges needed to melt and smelt metals is an exacting engineering process. Carbon is an Important industrial tool in such electrothermal and electrolytic application. The film explains the many operations in this exacting machine craft, from raw materials through calcination, extrusion, baking, graphitization, and finishing, required to build into carbon and graphite the necessary electrical conductivity and mechanical strength."

Ohio THE ELECTRICIAN, Mahnke 1942 llmin sd (Your life work) $50 621.3 Jh-sh Guide Produced by Vocational Guidance Films "Shows and describes in comprehensive, rather than detailed, fashion the work of the electrician in three major fields — power and lighting, communication, and transportation. "Many special jobs are shown and described, including the work of the top-ranking graduate electrical engineer. Suggested sources of training are described while the Interior of a trade school with student 'learning by doing* is shown. "It will motivate students who are Interested in a particular type of job to investigate the field in more detail. The film can be used in science and social studies classes to show the Importance of electricity and electricians in an industrial society." L. C. Larson in Ed. screen HERITAGE FOR VICTORY.
