Hi, I'm attempting to lash-up a K-Line TMCC Mikado with a Legacy C-420. I've done it before many times, and it's always worked. When I build then program the train, the Mikado doesn't signal a whistle. And when I go to drive it, only the C-420 does anything. Although the mikado is the lead engine, the C-420 blows its horn when I pull down the slider. The mikado works perfectly on its own though. I'm running legacy version 1.6.
Thanks
