The main purpose of this paper is to show how motions of human susceptibility to vibration can be related to track accuracy. It is hoped to give some impetus towards standard methods of specifying characteristics of track, vehicles and human response by quantitative studies. Present data is more extensive for vertical vibration than other modes. Vertical disturbances, therefore, are considered, but in the manner of indicating means, which, with further knowledge, might be applied to other modes of disturbance, and ultimately to varying postures of a passenger. One might start from either pole. That is by taking a given specification of track accuracy, or, alternatively, taking given criteria for passenger comfort. To commence from concepts of passenger suspectibility and derive appropriate track standards has seemed preferable. Rather more international unity is discernible in specifying human reaction than in defining a standard for track. It is also more logical to suppose that engineering standards might be improved by future techniques, whereas human beings remain unchanged.
