With the Spectrum locomotives  (and for that matter, for BLI or others) equipped with sound, is there any synchronization of the chuff rate with the movement of the train? I was watching a friend's C&O Spectrum DCC equipped locomotive last night, and it was not synchronized. However, he was running it on DC (the layout isn't finished yet.) I was wondering if the synchronization might be tied in with the DCC. I guess I would have to say that I was surprised that such a nice looking and running loco was so "out of synch". Any info would be appreciated.- Mike S

Sheldon, I really liked some of the thoughts expressed in the multi-throttle article you referenced here. As I've been checking out options, I have been looking at the MRC power packs. Do you know what the differences are between the older (I assume) 2800 Dualpower to which the article refers and the newer (also assumed) Tech 4 Dual Power 280? I've only been able to get technical specs on the 280. Also, do you have any other sugestions for a "standardized" power source for multi-throttle operation? I'd appreciate your thoughts.- Mike S.
