Congrats on receiving your MTH equipment!
I am afraid you are going to have to live without that American Freedom Train T1, at least for now. In my adulthood, I have purchased many things that I drooled over in Lionel catalogs when I was young -- they came many years after I first decided I wanted them, but somehow the long wait makes it even sweeter.
Just tell yourself, "Someday!" In the meantime, have fun running the trains you have!
