摘要:
Resilient support means for securing a rail to a rail bed comprises a base member, a rail location member and resilient mounting means acting between the base member and rail location member.The rail location member has side portions which are inclined relative to the rail abutment surface so that lateral steering forces experienced by a rail result in a combination of shear and compression forces in the resilient mounting means.The side portions may be inclined at any angle in the range from 15.degree. to 45.degree. preferably 30.degree..The side portions may be inclined upwards and outwards relative to a center portion or they may be inclined downwards and outwards relative to the center portion.The rail location member has means for directly securing a rail to the rail abutment surface.The mounting means may comprise a single element or a plurality of elements made from a suitable elastomeric material.
