so was running my k4 today when railsounds stopped working strange. Restarted everything ran it again. Lights began to. Blink no control. Troubleshooting began. Clean track clean pickups clean wheels. Still same problem. Tested 5 other steamers. All legacy. No problem. Next step I believe would be to take the cover off and make sure all wires are in tact?? Any other suggestions.
Thanks
