I wish I could drive across town to see what is of interest to me, but for me anything that you would have seen on the rails in early 90s will definitely run on my railroad, I don't really have much industry but do love to watch runthroughs the longer the better, I know in real life long trains can be a pain especially when you are sitting at a level crossing and in a hurry to get somewhere but even then you can get out of the car and enjoy the noise and smell of railroading in it's purest form.
I really don't worry about rivet counting but I do try to stay away from 50 foot boxcars with running boards and any thing with BNSF on it, just a little past where I like.
