Abstract

A support for the sliding motion of the moving blade of a set of railway points comprises a rigid foundation for a solid pad fitted with a central pillow having a base of rubber and a surface layer of low friction material, pref. PTFE, opt. impregnated with a lubricant. The pillow is sized so that the blade is raised clear of the main block while traversing the support, riding on the low friction surface, but the pillow compresses for the solid pad to support the position of the point blade level with the adjacent track as the wet. of a carriage passes over the point. Routine cleaning and greasing of plain metal pads is avoided.
