Abstract Abstract：Research purposes： In the domain of regional railway, the turnout is an important part of track structure and will affect the line design standard. In the urban railway transit, the main line turnout has lower passing speed, but in the national railway, the main line turnout has higher cost and poor in economy. To meet the needs of Wenzhou regional railway S1 line construction standard with speed 120 km/h, it needs to do research work and develop the suitable turnout product for Wenzhou regional railway which combines the characteristics of turnout of urban railway transit and national railway.
Research conclusions：(1) In the urban railway transit, the 60 kg/m rail No.9 turnout with fixed point rail exists harmful space and has lower passing speed. The movable portion of 60 kg/m rail No.9 turnout with moved point rail is too short, which can induce over switching force and inadequate displacement, as well as influence the track safety. Therefore, the 60 kg/m rail No. 9 turnout does not meet the regional railway requirements. (2) Through the comparison of rail horizontal alignment and frog type analysis, we obtained that 60 kg/m rail No.12 turnout with improved horizontal alignment of national railway GLC (08)01 and curved rail, moved point rail can meet the requirements of construction standard of regional railway;. (3) The fastener of 60 kg/m rail No.12 turnout with moved point rail uses the double elastic design with rail plate hard and elastic plate soft, which can make the fastener has good constraint capacity, low stiffness and adjustments. (4) The research results can provide some references for the design scheme of turnout for regional railway.
