Report "I am constructing a standard gauge lionel layout with 223 non derailing switches. I would like to rewire them for external power rather than track power. In Classic Toy Trains mag I believe this is possible but cannot find a reference article with details on how to dismantle the switch, rewire diagrams etc. Any help or reference would be appreciated. I also read Greenburgs prewar repair book but did not find any helpful info. Thanks"
