Good question, Bill! I have never ordered BTO from Lionel, but from what I have seen over the years, Rusty has stated the situation in a nutshell perfectly.
I know I am showing my age, but every time I see Lionel's acronym, BTO, I always think of Bachman Turner Overdrive. I guess it is fitting, Lionel is Taking Care of Business!! BTO is the only rock concert I ever attended; Pittsburgh Civic Arena - Summer 1974. A classmate and I drove down right before he left home for the Marines.
