Beta testers most likely know this already but:
My power & control system is entirely MTH (Z-4000, WiFi & DCS) I upgraded to all the latest editions (6.1). I find all functions work fine with the exception of Quillable Whistle. If I attempt to use this feature, the engines will: Quill just fine in this mode, quill one time then no whistle sound at all, quill but at a drastically reduced sound level, or cause the engine to accelerate rapidly out of control (the only way to stop this is to move to another engine and activate the emergency stop) This is completely random among my steam engines (all Premier & mix between PS2 & 3)
I know I have addressed this somewhat before, but I have one thing i’ve neglected to note in prior posts. I left the ‘magic lights’ on my layout, even though I upgraded to the latest TIU. I don’t think this would affect one way or another. I left these installed because my layout’s signal strength is a steady ‘10’ throughout.
Thanks
