Lego compatible replacement couplings for 80s trains - Ersatz-Kupplung für Lego-Zug aus den 80ern

Around 1980, Lego built trains powered by a 12-volt transformer. Unfortunately, Lego discontinued these trains at some point and switched to trains with a 9V battery. I think this change was not ideal for a toy, as it requires frequent battery replacements. The train likely hit the market in 1980. I played with it for years, and it was my favorite toy for an extended period. Now, my children build the train once a year, and every year it runs for hours under the Christmas tree. Replacing those batteries would be expensive – imagine kilos of them! Over time, more and more tracks and parts broke due to being stepped on occasionally. Couplers got broken too. This made the train smaller each year. The rails or spare parts are no longer available in stores. The only way to create compatible tracks for the 40-year-old trains was to build them from scratch. No sooner said than done – I constructed them in an afternoon. You can download the result. While the new tracks aren't perfect, they work flawlessly and allow the train to run again. It's fun to see how a 40-year-old toy still touches children's hearts today. Have fun with the old Lego train!
