So I recently decided to try out O scale for my newest layout ,( all previous layouts have been HO scale) I'm using all lionel post war track and accessories.  I'm having problems with where I should put the insulator pins on my turnouts.  I have about 12 turnouts on the entire layout and can't find any YouTube videos that address the exact issue in facing.  I have a couple spots on the layout where I hav two turnouts back to back facing opposite directions and im not sure where to put the pins on the two. Any help would be greatly appreciated
