I have two Athearn Genesis F7A, one with a NCE DASR decoder and one with Soundtraxx DSD-100LC decoder. the NCE one runs quieter than my atlas GP-40's ( Master Series with Lenz decoders ) The Soundtraxx F7A makes a lot of noise
, but it's the engine (decoder ) sounds and of course the loud bell and five chime airhorn ( can be set for single chime,three chime or five chime ), dynmatic brakes sounds, diesel exhaust sound gets louder as it notches up to top speed and lower as it is brakeing and upon slowly stopping, engine wine spins down to idle. ( pretty cool ).
So I believe the new "Genesis series" are quieter running ( elect. motor and gears ) than the older series of any of the Athearn f7's. But thats just my opinion, but if you want them to be heard.........put in a sound decoder and have a blast ( Oh yeah--Blast--get it
) aw never mine I'm going to bed. :sleeping:
