Applied Rail Research Technologies (ARRT) Inc.

ARRT Inc. is an internationally-recognized safety driven railway engineering consultancy firm. Our team of industry experts, specialists and associates provide practical solutions through investigative research and analysis to the most difficult railway engineering problems. About ARRT Inc. Established in 1992, ARRT continues to support the rail transportation industry through publication of its engineering, research and development activities as well as through internationally recognized seminars, conferences and lectures. ARRT is active in American Railway Engineering and Maintenance of Way Association (AREMA) committees and has made significant contributions to the recommended practices in the AREMA manual for track engineering. ARRT provides engineering support in cases involving rail failures, product failures, and vehicle component failures. ARRT is innovative and nimble in its approach to solving problems and breaking down the complex sciences that form the bases for its recommendations. ARRT focuses on safety. We specialize in designing solution-driven track systems and developing standards based on the most modern methodologies available to ensure optimal track/train interaction and component life. As a key developer of innovative track technology, ARRT combines analytical tools available in Computer-Aided Design, Finite Element Analysis, and event simulation with data from laboratory and field-testing. Combining this with real-world experiences from derailment investigations and failure analysis, ARRT is able to design better track solutions. ARRT's investigative research team in cooperation with the railway industry and regulatory agencies encourages the use of rail as a dependable and cost-effective mode of transportation in North America and abroad. Our goal: to assist the railway industry to remain profitable in this era of changing transportation priorities. ARRT ASET Software Traditionally, railways determine track superelevation based on the balanced speed of one axle and then reduce the resulting value by an arbitrary number called "unbalanced superelevation." This does not consider parameters such as multiple vehicle wheels, articulation of the train, train action, power location/distribution in the train, track curvature, grade, and thermal effects. Proper track/power asset management cannot be achieved without super-elevation and power distribution policies that respect these parameters. ARRT has developed and calibrated a track/train interaction software called Advanced Super-Elevation Toolkit (ASET) that considers all the parameters ignored by current standard practices. Ideal for scheduled railroads, ASET results are accurate and timely. ASET has Worldwide patents pending. ASET Modules • ASET/SE computes the ideal superelevation for any traffic mix over any terrain • ASET/SP optimizes speed profiles along any given route • ASET/DP determines the distributed power needed to maintain desired speeds Features & Benefits • Handles and accumulates bi-directional traffic results • Accommodates distributed power anywhere along each train • Identifies problem areas • Provides draw bar forces • Minimizes track forces • Reduces damage to track asset and derailment probability • Increases fuel savings and ROI For more information, please visit our web site at www.arrt-inc.com
