Greetings! My father stored a Lionel "O" gauge train set in my attic for over 25 years, which has not been used in over 40 years. I wish to try to set it up now. There are no instructions with the set, are any available online or in this forum? I was able to lay track out in a double loop with two 022 switches. My recollection was the ZW transformer powered each loop separately for two trains. I have checked for continuity between the rails and there is continuity between the inner and outer rails but not with the middle rail. So my question what is the point of the insulating pins in the switches if they are only in the inner rail? It would make more sense to me if they were in the middle rail but welcome an explanation. The next question is how to attach wiring to the track, specifically what are lock ons? I have two special tracks with electrical screw posts and 5 rails with a control switch presumably to unload logs from a car on one. Are these lock ons?  Tried to upload photo but upload folder full. The box says remote control track set. Thank you in advance. I did try searching but could not find answer to my question.
