      <title>MONITORING THE EFFECTS OF THE TYNE AND WEAR METRO</title>
      <link>https://trid.trb.org/View/174808</link>
      <description><![CDATA[This report describes the studies which have been initiated by the Transport and Road Research Laboratory to monitor the impact of a new rapid transit system. the Metro, on the metropolitan country of Tyne and Wear. The research is concerned with the effect of the transport changes on travel patterns, land use activities, property values, and pressure for development within the county.  The extensive 'before' surveys are described.  The first section of metro (Haymarket to Tynemouth) opened in August 1980 and limited monitoring exercises will continue until the system is fully operational in 1984.  (A) (TRRL)]]></description>

      <title>BUCKLING OF RAILWAY WAGON FRAMES</title>
      <link>https://trid.trb.org/View/161007</link>
      <description><![CDATA[This paper presents the analysis of the three dimensional space frame with arbitrary configuration and loading.  The conventional stiffness method is modified into an iterative technique to take into account the effect of axial force in magnifying the flexural deformations.  The theory predicts the buckling loads of the frame of box-type freight car and 4-wheeler undercarriage frame used by Indian Railways.]]></description>

      <link>https://trid.trb.org/View/80961</link>
      <description><![CDATA[Designing the new cars was a question of scale.  With only 33 cars required, it was desirable to use established technology, but the tunnel diameter and track curvature decreed that no existing design was suitable. The article describes areas of the cars made special to the 'mini' system to overcome tunnel and track constraints.]]></description>

      <description><![CDATA[The article describes the mass transit system to be built at London's Gatwick airport in the United Kingdom.  The people mover track consists of twin concrete running surfaces for the rubber-tired load-bearing wheels with an I-section guide beam between them.  The Gatwick installation has twin tracks with a walkway between them.  Rubber-tired guide wheels clamp on to each side of the guide beam, on top of which is mounted the current collection assembly.]]></description>
