Mine is doing the same thing. It's like an antenna/comm issue. Start-up fine. Everything works great, until it starts moving. Whistle underway is sporadic at best. Speeds are crazy. Hard to start and stop. Loco sometimes stops on its own and goes into reverse. Other legacy locos that I have work great. sigh...
