Just got the MTH 20-21188-1 (Amtrak (Wave) Genesis Diesel Engine). I don't have a layout yet so have a short test track.
Put this loco on the track and noticed when it goes over the Lionel 6-12020 (Remote Uncoupling Track) the uncoupling button in the middle of the track is raised just enough to cause the loco to raise up and the wheels spin a bit. The button is abut 1/16 inch higher than the track. It doesn't seem to effect the operation of the loco other than the wheel spin.
Anyone else seen this?
