The National Track Mechanical Switchman converts the ordinary hand throw split switch into an automatic or spring switch thereby permitting trailing movements without stopping to throw the switch. It is used on passing sidings, departure ends of yard tracks, ends of double track, and approaches to bridges.

The National Track Mechanical Switchman is connected to the switch stand and switch in the same manner as a connecting rod. The mechanism permits the normally closed switch points to be forced open by a trailing movement, where they remain until the last wheels have passed. The mechanism then returns the points to the fully closed normal position.

  • Self contained unit combining the spring head and oil buffer into a single unit

  • Switch points can be thrown manually with no resistance

  • Designed to permit trailing from either track

  • Switch points return to their normal position in 10-12 seconds with a 4 3/4″ head rod
