Hello, fellow railroaders. I feel silly asking this as I am an EE by profession but can anyone with access to a 1950s era American Flyer s-gauge instruction manual explain why the hookup for a single reverse-loop using a manual DPDT switch (not a reverse loop relay) apparently has to be more complicated than required? In addition to a track switch (turnout) it requires six track insulating pins and presumably three track terminals. I understand how it operates in this manner but, in addition to a DPDT switch, why not just make use of the two-train option on the turnout and a single insulated track section? Thanks for your time and comment. Sincerely,
