   Keywords : dynamic vehicle-track interaction; turnout; switch crossing; wheel wear; wheel-rail contact geometry;

   Abstract : Turnouts (Switches & Crossings) are important components in railway networks, as they provide the necessary flexibility for train operations by allowing trains to change among the tracks. But the turnout’s geometry with discontinuity in rail profiles and lack of transition curve causes additional wear both on track and on vehicle. READ MORE
