:thumbs_up: Today I just tested my new Challenger on 9-3/4 inch Kato unitrack and it ran fine. It was cool to listern to. One ? for those with Lenz dcc how do you get to hear the other sounds? I can only hear a couple. Do I need to turn on more functions. Overall I am very happy with this engine. Thanks for your help. Alan
Alan: The Lenz 100 system has 12 functions that you can control. Most of the other sound noises will be heard intermittently when the loco is at rest or is running. Turning on F6 when the loco is slowing down will operate the brake squeal. F6 operates conductor as loco start up. The chuff sounds you can change as well as steam hiss. Stay cool and run steam.....
