I picked up the new Legacy W&LE Heavy Mikado last week and ran it this past weekend. I ran it with a moderate load (20 scale plastic freight cars with die-cast trucks). After a little while of running, the engine slowed to a stop and behaved as if it was in neutral (cab light came on and headlight dimmed). I picked up the Legacy remote and it still indicated that the engine was running at the speed step I set it at about 15 minutes prior (around speed step 70). I adjusted the throttle and the engine slowly started moving again. Figuring it was a fluke or maybe too heavy of a load, I pulled off five cars and got it up to speed again. About 25 minutes later, it did the same thing again. In the couple of hours I ran it, it did it six times at random time intervals. Please note that I have several other Legacy engines and none of them have ever behaved like this at home or on any other layout I have run them on with Legacy or TMCC.
Has anybody seen this type of behavior before or what might cause it? I suspect there might be something wrong with the engine.
