Fwiw, I pulled the 2001 volume 1 catalog out. Here is the info on the Pacifics.
Standard stuff for the time with TMCC, odyssey with 32 speed steps, Railsounds 4.0 with 2 chuffs per revolution and basic crewtalk/towercom (“You are clear for departure” when hitting button 7 and unintelligible chatter when hitting button 2). Also of note is that it has a fan driven smoke unit but Lionel didn’t have synchronized smoke until later, so it doesn’t “chuff”. It just stays constant.
