I used to be mainly steam but as of late, I've gotten more and more into diesel locomotives. I still love steam but the diesels are cool too. I'm kinda curious as to what everyone's favorite style of diesel locmotive is. I'm not going to try and make a poll or anything because there are too many to list but I think it would be intersting to see where everyone's tastes lie. For me, I think the old F7's and F9's are by far the coolest.
