I recently purchased used (mfg in the 1990's) a LGB 5006 and 5007. It came without a wiring diagram. Although I have gotten power from the end terminals to run trains, the two terminals in the center have me confused. What are they for and how are they to be wired into the layout? Is there any place that I can purchase the original instructions? I went to the LGB site but it was in German. Thanks!
Since you're asking about LGB, you obviously have G scale. You might get a faster answer by asking this question on the Garden Railways forums.
