I recently purchased 2 new 0-4-2 Porters with sound & a 2-6-6-2 Mallet along with sound. The Mallet sounds absolutely spot on just like the rest of Bachmann's sound equipped lokies, but the porters have a tendency to to make crackling sounds when multiple sound effects are played together. (Ex: Chuffing, brake squeal, & whistle.) Does anybody know if this is a problem with the sound exciter(s) or should I purchase a DCC system that can toggle the volume settings of my engines? Any replies are much appreciated!

I'm Thinking about purchasing the Inside frame 4-4-0, and am wondering if the factory installed tsunami and speaker from the On30 ten-wheeler will fit into the 4-4-0's tender with out major modification. I tried looking threw the parts diagrams here on the bachmann site, but the inside frame american's pdf takes me to the modern outside frame 4-4-0's. Just wondering if anybody knew. Recently bachmann stopped producing this 4-4-0 and I need to pick one up before they're all gone!

Thanks! ;
