Another thing that hasn't been mentioned, is that the new 2019 Big Boy's are not Vision Line but instead Legacy. Going a little deeper, the VL BB has Whistle Steam, dual-stack smoke units, blowdown smoke, depleting coal load, and as detailed as if it was just put into service. Whereas, the 2019 BB has one stack smoke unit, whistle steam, no blowdown smoke, no depleting coal load, and is made to look as 4014 looks today. This means, two dynamos on top of the boiler, no cooling tubes on the handrails, glossier finish on the boiler, Big Boy on the front of the smokebox door (on some not all), no ashpan, and no red knobs on the firebox. Now, both do have dual speakers, one being in the tender and one in the engine. Also, the sound system in 2019 will probably be the same as the VL BB. Personally, I am glad that I was able to get a VL BB since no one fully thought that Lionel was going to make a semi-scale and Legacy version, but it is really up to you on how much you want to pay. In other words, you are paying over $4,000 for the collectability, and features, whereas you are paying $2,000 for an engine with fewer features but more looks.
