Edison, by Edmond Morris

Edison by Edmond Morris is an American business biography, containing points of both historical and geographical interest. It's also still possible to obtain a copy of a High School drafting textbook that teaches you all the mechanical part of the train he invented, but I don't recommend the nine-month bridge school AutoCAD version, which is typically a siphoning portal for the software license and doesn't give you any drafting desk pencil and paper real world true dimensions measuring and art drawing experience. Also, the student license you get with the AutoCAD class expires after three years, and you loose all your files. Learn how to draw for real instead of wasting your money on that.
