Heavy duty, single acting, serviceable damper designed to slow the return of the wing rail on spring frog switches. Spring frog switches are usually remotely located. The spring loaded wing rail is biased to the main track, so as the wheels of trains approaching on the side track hit the wing rail, it springs open to allow the train through. The damper slows the return of the rail for about 30 seconds thus reducing the number of wheel/rail impacts and so reducing wheel/rail wear.
