has anyone else seen this? I have a new Athearn Genisis SD70ACe and the lead axel on the front truck keeps jumping the track. It always shows up in the same spot on the track, at a joint. If I run it backwards, it doesn't happen. We're the Genisis locos light in the trucks? Would adding weight help? This is on the joint between the first 2 curve pieces, I've filed the joint to where is is completely smooth. Anyone care to throw out some ideas? I notice if I push the truck up towards the frame there seems to be a catch but I filed that down as well. Any thoughts would be appreciated. I like the loco but if it keeps this up it will be relegated to lash-up status and not the lead loco. Thanks, Dale
I have had this problem. The rails were too close together at the joint making the truck climb up the rail. Have you measured the gap between the rails? Sent from my GT-N8013 using Tapatalk
I had, literally, the same thing except with a Dash 9... turned out to be bad track... even though every other loco I had, even another Dash 9, would have no problems. Ended up cutting out a 5 inch section of track and relaying it. JMS
Sounds like a classic guage problem. Bet the track is just a hair to narrow and the truck a hair to wide and the combo is trouble.
