Used USA Trains ALCO PA-1/PB-1 SP Daylight dual-speaker Phoenix sound

Not just any USA Trains PA-1/PB-1 set, we added Phoenix sound and didn't stop there. The sound card is in the B unit, but the A-unit speaker is connected via easy 2-pin connection, allowing TWO speakers to pump out sound. Both units are powered, so there are FOUR motor blocks pulling your train. The sound file is all ALCO diesel, with the distinctive clattering of the ALCO power plant. Enjoy the photos and video.
 
Tested and ran smooth. Sound and movement started at only approx. 3 Volts on our Bridgewerks controller. Very little use - check out the wheels which look new. 
 
Flaws noted: a small detail piece is broken off each roof. These are available at low cost from USA Trains. One set of hoses is broken off the rear. Sorry, clumsy of me.The B nit smokes but the A unit seemed to let out only wisps. Maybe I need to work with it a little more.
 
 
This engine pair is really nice, and a very attractive livery. At home pulling heavyweight, streamlined or freight consists. SP liked ALCOs for their mountain pass routes, where the high-tongue ALCO engines handled the loads better than EMD diesels.
