This conclusion, revolutionary In the transportation field, has been announced at the Omaha headquarters of the Union Pacific. It Is based upon the formal report of Ralph Upson, noted aeronautical engineer and Itream-Unlng authority, who in company lth a group of scientists, has been making exhaustive wind tunnel i vsts of models of the new train. These tests, to determine wind resistance and friction at high speeds, were the first ever made In vientiflc history on a stream lined railroad train. After the contours lor perfect tream lining were established an txact scale model of the new train, eight feet In length, was built by the Union Pacific and Installed as a part of the Chicago & North Western Railroad exhibit at the Century of Progress exposition at Chicago. The exhibit, one of the unusual features of the Travel' and Transport building. - Is attracting at-tracting wide spread attention of dentists, transportation experts and the general public. The final model varies slightly from the original design which focused International attention when It was announced by the Union Pacific some weeks aao. The principal changes dcv.-loped by the tests resulted in the rom-plete rom-plete shrouding, or cover;).? of the articulated trucks o; r -- - -i and In some alteral.ous i:i t:ie design of the engine cab. The altered cab de.sian not only provides pro-vides for perfect stream lining but also will give the engineer of the train 270 degrees of vision a greater vision than a train engineer engi-neer f. before has haJ. The effect of the changes are ! such that the train, traveling' at Its maximum speed of 110 miles per hour, wiil jab a clean hole through the air and iet the air close again behind without any fuss and tumid!. Tlie 3-c;r aluminum alloy, tubular-shaped train is now be-ins be-ins built in Chicago by the Pullman Pull-man Car and Manufacturing Co. When completed the entire train will w.MMh approximately 80 tons ivhxh Li the v. ? "lit of one modern v'v i . c?.r.

In operation the train will "hug the ground", the bottom of the cars being but nine and one h.Jf inches above the rails and the top of the cars eleven feet above the rails. This low center cen-ter of gravity will add materially mater-ially to comfort at high speeds so that the train can negotiate curves safely at higher speeds than present trains. The 12-cyllnder, 600 horse power, V-type distillate Internal Inter-nal combustion engine Is now under construction at Cleveland Cleve-land by the Wlnton Engine : Corporation, subsidiary of Gen-J Gen-J eral Motors. Distillate, which j Is used for fuel, Is non-explos-; Ive. ' According to announcement of the Union Pacific the operation opera-tion of the new train is sched- ; uled to begin on December 1. i' .
