Legacy vs Vision Line

For the specific case of the Genset, the Vision ones have 3 independent smoke units.  

For the later non-Vision ones, I believe it is one smoke unit, so all 3 stacks operate simultaneously.

Dave is correct, I have the VL genset.  The Vision Line one has really nice detailing, actually in some cases, too nice.  All of the extra detail is fairly fragile...  My major complaint is the really neat flapper exhausts only work for a short time before they get gummed up and have to be cleaned.  However, they are soooo cool when they do work.

The single most important difference for me in my VL PRR Centipede AA set is both units have full power, smoke, and SOUND.  Legacy AA sets have only one engine with power and sound; the other is a dummy. (Also, if there was a B unit available with power it did not have sound.)  This required that you buy two complete AA sets to get two powered and sound units.  Buying two Legacy sets to get power/sound in both units drove the cost up to near VL prices.  And you would not get the VL feature of the two engines being out of sync which is really neat.

Because the Centipedes had full power, smoke, and sound in each unit I assume all future VL AA, AB, and even ABA sets will too.  If they issue them in PRR, I will buy.

PS: they do not need to be brass.

Point of information:

There never was a Centipede "B" unit, real or model.

The Lionel Legacy "NON VISION" Centipede single A never came in AA sets...they sold A unit only and it is identical to VL Centipede front unit BUT it has TWO electrocouplers not one as in the VL single A unit (the VL centipede had two electrocouplers total for the AA set)...FYI
