Parameters that characterize the effect of wheel impact loads on rail behavior are examined in terms of system variables such as geometry. material properties, loads, and track conditions that affect stresses which in turn control the mechanism, probability, and mode of failure. Quantitative descriptions of wheel/rail load characteristics typically encountered were obtained from a review of the literature and results from recent laboratory and field measurements. 17.

Two of these programs that were managed by the FRA/Office of Research and Development (ORD) and the Transportation Systems Center (DOT/TSC) of Cambridge, MA, the "Characterization of Wheel/Rail Loads" and "Analysis of Service Stresses in Rails", were both conducted by Battelle's Columbus Laboratories. More recent work on impact loads has been conducted under Development of Safety Criteria for Evaluating Concrete Tie Track in the Northeast Corridor for the DOT/FRA Office of Research and Development. Special thanks are given to Dr. Oscar Orringer of DOT/TSC and to Mr. Howard Moody of DOT/FRA for their contributions and suggestions over the course of these studies. Thanks also to Robert Prause, Dr. S.G. Sampath and Harold Harrison for their contributions and encouragement as project managers for Battelle.

  • The Evolution of the Steam Locomotive, 1803 to 1898 (1899)
    > g s J> ° "^ Q as : F7 lA-dh-**^) THE EVOLUTION OF THE STEAM LOCOMOTIVE (1803 to 1898.) BY Q. A. SEKON, Editor of the "Railway Magazine" and "Hallway Year Book, Author of "A History of the Great Western Railway," *•., 4*. SECOND EDITION (Enlarged). £on&on THE RAILWAY PUBLISHING CO., Ltd., 79 and 80, Temple Chambers, Temple Avenue, E.C. 1899. T3 in PKEFACE TO SECOND EDITION. When, ten days ago, the first copy of the " Evolution of the Steam Locomotive" was ready for sale, I did not expect to be called upon to write a preface for a new edition before 240 hours had expired. The author cannot but be gratified to know that the whole of the extremely large first edition was exhausted practically upon publication, and since many would-be readers are still unsupplied, the demand for another edition is pressing. Under these circumstances but slight modifications have been made in the original text, although additional particulars and illustrations have been inserted in the new edition. The new matter relates to the locomotives of the North Staffordshire, London., Tilbury, and Southend, Great Western, and London and North Western Railways. I sincerely thank the many correspondents who, in the few days that have elapsed since the publication: of the "Evolution of the , Steam Locomotive," have so readily assured me of - their hearty appreciation of the book. rj .;! G. A. SEKON. -! January, 1899. PREFACE TO FIRST EDITION. In connection with the marvellous growth of our railway system there is nothing of so paramount importance and interest as the evolution of the locomotive steam engine.

In this methodology to find the optimized, with respect to safety and comfort, lateral damping of both the primary and secondary suspensions of a bogie system for a train. Under competition from other forms of transport, railway operators are seeking to offer their passengers ever-increasing train speed and comfort. It is known that considerable improvements to train speed and passenger comfort could be obtained by the use of full-active suspensions, in which the energy flow in the suspension is controlled and augmented by an external source, using a technology similar to the one developed in the automotive world. Keyword: - Bogie suspension, Damping, g-force, centrifugal force, Tilting Train Mechanism 1. INTRODUCTION Transportation is the basic need of daily life due to which all the services are easily and on a systematic way. One of the most considerable examples of the transportation is the train.

  • Modeling China's — and Now Iowa's — Mighty QJ 2-10-2'S
    February 2007, Volume 75, Number 9 Modeling China’s — and now Iowa’s — mighty QJ 2-10-2’s After being replaced by diesels in their home country of China, a few of these modern, heavy-duty steamers have found their way to the American Heartland / Robert D. Turner ntil the end of 2005 one last place remained on Earth where big steam locomotives in substantial numbers were running in regular freight and passenger service on a year- round basis. That place was northern China, and in particular the autonomous region U of Inner Mongolia, to the northwest of Beijing. There, on the JiTong Railway, (often written Ji-tong) a stable of rugged 2-10-2’s—coal-fired and fire breathing—were still racking up ton- miles every day in an uncompromising display of first-class railroading. These impressive machines were China’s QJ class locomotives. QJ is short for Qian Jin, or “Advancing.” It comes from the Chinese revolutionary slogan, “revolution is the locomotive pushing human history forward.” Revolutionary rhetoric aside, which I am sure loses something in the translation, it is fair to say that in years to come the QJ will be remembered as one of the most interesting and important types of steam locomotives developed in the 20th century. In fact, two now reside in North America, having been imported by Railroad Development Corporation in June of 2006. They were moved to the Iowa Interstate Railroad soon after their arrival and were operated on its rails over the weekend of September 14-17, 2006. I met my first QJ early in 2001 on China Rail just before they were retired, and then began to explore the JiTong Railway, where QJ’s were in abundance.
