The　milled　shape　of　point　blades　is　one　of　the　main　factors　causing　structural　problems　with　railway　points　(also　known　as　turnouts　or　switches).　Choosing　the　right　type　of　milling　for　point　blades　can　improve　train　running　performance.　Based　on　wheel-rail　system　dynamics,　a　vehicle-points　dynamic　model　with　various　milling　methods　was　established,　from　which　a　selection　and　evaluation　method　for　milling　was　proposed.　The　service　performance　of　four　milling　types　was　compared　and　combined　with　point　blade　robustness　to　provide　a　comprehensive　evaluation.　It　was　found　that　a　small　rate　of　railhead　width　change　for　an　oblique　tangent　point　blade　resulted　in　better　running　performance　of　trains.　The　oblique　secant　point　blade　caused　an　abrupt　change　in　the　rail　layout,　which　reduced　train　running　steadiness.　The　railhead　widths　of　longitudinal　secant　and　longitudinal　secant-oblique　tangent　point　blades　increased　quickly,　and　the　corresponding　dynamic　responses　were　at　an　intermediate　level.　The　proposed　selection　and　evaluation　method　for　milling　types　took　into　account　the　dynamic　characteristics　and　structural　durability　of　the　points.　It　will　be　beneficial　in　selecting　an　appropriate　milling　type　for　points　blades　according　to　their　service　requirements.　　©　2023　Emerald　Publishing　Limited:　All　rights　reserved.
