      <title>A FIELD EXPERIMENT ON THE "TRAIN DRAFT"</title>
      <link>https://trid.trb.org/View/4882</link>
      <description><![CDATA[There exists a gusty wind when a train passes called "train draft".  The velocity of this wind is supposed to increase as the train speed increases.  This factor is of importance to safety of railroad maintenance workers as train speeds increase.  The article discusses the phenomenon, and the means used to measure the methods of measuring the wind velocity.  The results of a model experiment are compared with one in the field.]]></description>

      <title>TRACK STRUCTURE FOR HIGH-SPEED TRAFFIC</title>
      <link>https://trid.trb.org/View/4959</link>
      <description><![CDATA[Results of tests of factors related to a speed test of equipment at 200 km/h are studied with effects of ordinary track, track on a solid bed (without ballast) an expansion and insulated joint, a PC sleeper, deformation of loamy embankment, ground vibration and finally, train wind force. The second section is devoted to thermit welding of various types of rail and standards to be followed.]]></description>

      <title>RAILWAY TRACK STRUCTURE FOR HIGH-SPEED TRAIN OPERATION</title>
      <link>https://trid.trb.org/View/4960</link>
      <description><![CDATA[The aspects of rail structure for high speed operations are discussed.  The drop test for rails, chemical and mechanical properties of rail steel, rail fastenings, PC railway ties (sleepers), grading of ballast, ballast agitation by train wind, and finally, the effects of loading and repeated water sprinkling on railroad embankments are discussed.]]></description>

      <title>HIGH SPEED ROLLING STOCK - QUARTERLY REPORT - 1962</title>
      <link>https://trid.trb.org/View/5004</link>
      <description><![CDATA[Article discussing the topic of high speed rolling stock and the unique design problems of high speed operation. Aerodynamics of design and such factors as wind pressure of passing trains, on pantographs.  Tentative car designs, factors of wheels such as axle strength, flat wheel and bearings are considered.  Finally the design of the main driving motor and temperature rise, rectification and driving gear are discussed.]]></description>

      <title>HYDRODYNAMICS OF PHENOMENA DUE TO PASSING-BY OF TWO TRAINS - QUARTERLY REPORT - 1965</title>
      <link>https://trid.trb.org/View/5071</link>
      <description><![CDATA[The investigation on such a flow became necessary in connection with the construction of the new Tokaido trunk line where trains will run at the speed of 200 km/h.  The calculated results (three-dimensional) agree with the actual data from the passing-by test of trains not only qualitatively but also quantitatively.]]></description>

      <title>FIELD MEASUREMENTS OF TRAIN DRAFTS</title>
      <link>https://trid.trb.org/View/5447</link>
      <description><![CDATA[Why does the train draft become a problem for us?  In other words, for what purpose or purposes are they studied?  The answer is that we want to know whether the human body standing near a railway suffers any danger from the passage of the train and to clarify to what extent the structures near the railway are influenced by train drafts.]]></description>

      <title>COMPUTER MODELS FOR RAILWAY VEHICLE OPERATION</title>
      <link>https://trid.trb.org/View/80152</link>
      <description><![CDATA[The paper summarizes the computer programs developed under the Track-Train Dynamics project, designed to study the dynamic interaction of rolling stock and/or train-consist with track.  The models describe the vehicle response on tangent and curved track and also discuss the phenomenon of lateral dynamic stability.  Results obtained from lateral, vertical and longitudinal train action models, are presented.  Analytical results are compared with field data. Possible application, of the computer program for train-handling and train-make up are also discussed.]]></description>

      <title>TRAIN RESISTANCE, POWER AND ENERGY REQUIREMENT OF M-U CARS</title>
      <link>https://trid.trb.org/View/4220</link>
      <description><![CDATA[Equations to be used in determination of multiple-unit train resistance, power and energy requirement are developed.  Curves are presented for air resistance in tunnels.  For open air the effect of wind speed and direction is also analyzed.  Methods are presented for energy requirement optimization.  Considerable energy savings can be realized by using these methods as guide lines for operational criteria.  This study extends the work of W.J. Davis, Jr., for all kinds of M-U cars.  The Davis equations were prepared and still are successfully used for conventional rapid transit train speeds and shapes, but not for high speeds and  streamlining.]]></description>
