Every new TSW version you mess up the sound of this loco. There is no voice output. No "Zugbeeinflussung" No "Sifa" No "Zwangsbremsung". All german routes installed.
So I have 3 different 146's and the top one behaves like you describe but the second and third seem to work properly. The second one doesn't use PZB Wachsam/Sifa pedal indiscriminately when pressing B/Circle so that's probably the best one. The order they're listed may be different to you. I'm on Xbox and your case might be different. Sorry if you already know all this. https://forums.dovetailgames.com/threads/tsw3-is-this-a-joke.58898/
