I have a Lionel legacy B&M T1, item 6-11386 (circa 2013). The problem is even at full volume at the engine and the legacy remote, the chuffing gets drowned out by (Atlas nickel) track noise. Meanwhile the whistle is very loud. Is there an internal trim pot to balance the whistle with the chuffing? That is the one thing I miss on Lionel systems- no individual sound adjustments.
