" Coupler Fixed ??? OK I have been using a short section of lionel track as a test track. This is the new style of track with the molded roadbed. Originally I had a Lionel powerpack plugged into the track. It's an 80 watt DC powerpack and the voltage on the track read 18.2 volts. So the lack of voltage wasn't the issue, but no matter what I did the rear coupler wouldn't open (although you could hear it). I later tried a MRC variable voltage DC transformer from the 90's. It's really meant for HO scale trains but it's rated at 160 watts and can reach 19 volts, again the front coupler would open fine from 14 volts to 18.3 volts (I never went above 18.3 volts) and the rear coupler wouldn't open. Today I decided I would take apart the rear coupler and have a look at it. Before I did this I set the train on my main layout which is powered by an old ZW transformer. Long story short with the old AC transformer both the couplers work great! Even with the voltage down to 13 volts. Lionel states not to use AC with bluetooth control. Thoughts anyone? "
New to trains and such, but i too have this little loco and rear coupler issue while using fast track. The front opens anywhere on my track but the rear one only opens when within 10 inches from powered track plug in. I guess i need to test the tract voltages around the track and the continuity? Any thoughts.
