LENGTH OF RAILWAY TRANSITION SPIRAL-ANALYSIS AND RUNNING TESTS

Report and analysis is made of length of railway transition spiral, to provide more information on fundamental factors related to the design of the spiral easement curves and the levels of acceleration suitable for the requisite comfort on diesel locomotive and modern passenger rail cars. Previous work and history are reviewed, and the problem is analyzed. Other topics considered include test procedures and instrumentation, passenger ride comfort, lateral forces on leading locomotive trucks, and effects of track variations. It is noted that reported results confirm British ride comfort results, despite more scatter in the plots of the current study here.
