There used to be and maybe still is a pretty cool show called "How It's Made" where they walk you through the end to end process for manufacturing all kinds of different products, often starting from raw materials. For our products, who created the molds for all of the great engines and rolling stock we buy? Where did they get the dimensions and details. I know we can go straight from CAD to the machine shop to create molds today but I would think that some of what we are buying of have bought was done by hand. Is there a video or other resource that shows how this was done? And who were the artists that did all the hard work?
Thanks!
