Points frog with main rail and no crossing track - has tilting ramp under branch rail and extension rail to raise wheel flange level

摘要

The wing rail (6) continues on to the branch rail (2) over a tilting ramp (8) to raise the wheel flange level (3). The area between the wing and extension rails (4) is formed as a flat track (5) to keep the wheel flange space requirement free for the main rail (1). The raising (3) of the branch and extension rails is by cutting the web, lifting the head and splicing with welded infill plates. ADVANTAGE - Avoids impact and breaking in noise on both main and branch lines.
