This thread made me rather introspective and I spent some time thinking about why I like both, and its for very different reasons. Interestingly, I like and run both due to these three concepts in my mind:
- I associate passenger trains with diesels - specificaly passenger diesels of the 1950s: EMD F3s and E8s and Alcos, Sharks, and the like.
- I like to run passenger trains because they are romantic, attractive (sleek, nicely painted, sometimes actually beautiful) and they remind me of the train-trips I took as a kid.
- I run freight trains because I like to run steam locomotives - they look so cool with their brutish shapes/size and equipment, and all those wheels and rods and valve equipment. I don't associate steam locos with passenger trains (even though I realize they pulled passenger service up into the postwar era, and have both a Dreyfus Hudson NYC train and Blue Comet train - passenger trains - on display in my trainroom). So I run freight behind the steamers since I want to run steamers - that is only/major reason I run freight trains!
I'm not sure this makes sense, or makes sense to others, but its why I run what I run.
