Recently had some over heat issues but back up and at it! I have a splitter coming out the back one rewired to the original track connectors and the other wire set I solder straight to the track. I can either run them together and help prevent voltage drops or run two separate trains. 3/4 engines each have a metal wheel motor and then a newer battery version wired to it. It’s not perfect but it does the job well. submitted by /u/Fugalisious [link] [comments]
