@sinclair posted:There are a lot of factors you must consider when it comes to mechanical design (Which I do for a living.), and the one you must always pay attention to is physics as physics will always win. And as a design engineer I am very impressed with what Lionel was able to do with these locomotives.
I will reply to your remark only by saying that, between the two of us, you are not the only one who is knowledgeable about physics and engineering.
