COMPARISON OF TWO TURNOUT DESIGNS IN REVENUE SERVICE

D D Davis, Joseph LoPresti

Open publisher page 2 citations

Abstract

The Association of American Railroads (AAR) is comparing the performance of an American Railway Engineering Association (AREA) geometry turnout to that of a tangential-geometry turnout in its Advanced Turnout Evaluation Program. The turnouts have been evaluated analytically using AAR's vehicle dynamic simulation model NUCARS, and results show that reduced-entry-angle switches will provide significantly-improved performance under freight traffic. The preliminary technical analysis is discussed in the paper.
