In response to a few questions from viewers of our engine restoration videos, we decided to produce an informative session about the different wiring techniques used by Lionel in their Prewar Standard Gauge and O Gauge Motors. Information is included about the Pendulum Reverse Unit of the 1920's. Also described is the wiring used for Locomotives with Manual Reverse.
