  • Abstract
    The regular efforts to enhance vehicle velocities and obtain even higher speeds on the railways
    need high quality track. The measure of track quality is the quality of the curves linking intersecting but multiple
    directional straight lines. Presently, transition curves are provided on track suitable for higher speeds to
    negotiate the contact stresses and dynamic effects generated due to lateral acceleration. Despite the less
    literature available on the area, methods exist for planning transition curves taking account of the dynamics of
    movement. Most of them are based on the effects or non-compensated lateral acceleration changes in such
    acceleration and the shock of sudden displacement, the resulting track curves being adapted to the proscribed
    basic geometry in most cases on a trial and error basis or by insertion of circular arcs. In an attempt to establish
    new ways of planning, this paper proposes a method for developing the curvature functions that are so important
    from a dynamic-point of view from a combination not just of the two fundamental factors- lateral acceleration
    and shock-but also taking account of geometric conditions and desired deflection angle.

    Key words: Contact stresses, Lateral acceleration, Non-compensated lateral acceleration, Transition curves
