I've loved trains, especially steam locomotives, since even before I got into cars. The strange thing about this is that while my car hobby exploded into an almost all-encompassing obsession that nearly takes over my life, I haven't learned nearly as much about trains in the meantime. This could be in part by the fact that cars are much easier for me to relate to: I see them daily, ride or drive them daily, and classic or otherwise significant cars aren't all that rare. I can safely bet that on an average day here in Michigan, it's more likely that I see a car I love than it is to see even a regular freight train on the tracks down my street.
