Abstract

See full text

An automatic switching system particularly adapted for railroad hobbyists whereby the complicated polarity switching usually required is eliminated. Apparatus is associated with each insulation point in a track section (block) to sense the direction of train motion and automatically conform the polarity of the next track block upon which the train will enter if the next block is of an opposite polarity from the prior block section from which the train has left.
