I test ran my first PS3.0 steam locomotive last night and it seems MTH has made improvements in steam chuffing and whistle effects - the chuffing was more deep sounding. The PRR banshee whistle had a background tone to it, like a 2-tone effect, but I don't think this was true quilling. Is there a way to actually quill the whistle? I have the latest software upgraded - 4.31.
BTW: Three of my PS2.0 steamers sound anemic - despite increasing volume - is this a sign that the batteries are depleted?
