hi guys! a week ago I decided to run my model train layout for the first time in two years and have noticed that my Piko H0 ICE 3 is making problems. not only does it barely pick up speed, but also it “eats up” all the electricity on the tracks. I measured the Volts on the track and when I use my two other locos, it usually says like 10V while running. but when I run the ICE, it measures only 0.5V on full power? does someone know how I can fix that? thanks :)
