Abstract
Model railroad layout with a length of track formed near the ends of the rails with gaps and connected to an electrical source and a control means to reverse polarity on the rails when the engine wheel bridges a gap.
Claims7
Model railroad layout for use with a direct current motor-driven engine, comprising
- a. a track having a finite length and consisting of two parallel rails, one rail having a switching means consisting of a gap in the rail adjacent one end of the track and the other having a switching means adjacent the other end of the track,
- b. a source of direct current electrically connected to the track, one rail being connected to ground and the other rail to the positive voltage side, so that current passes from one rail, through a wheel of the engine, through its motor, and through another wheel to the other rail, and
- c. control means to switch the polarity of the electricity applied to the rails to reverse the direction of the motion of the engine when it approaches a switching means, the control means reversing the engine when a wheel passes over a gap and electrically connects the rail on both sides of the gap.
