Call me shallow, but aesthetics is a big part of the appeal of railroads and modelling. I've studied my own reactions to locomotives particularly - almost have it down to a science. Unfortunately, that means that I can't summarize them. It would take a small book. Maybe I'll post some of that when I have more time. Anyway, I don't recall this forum having a thread like this recently, so... Which locomotives are attractive or just "look right" to you? And which are completely the opposite? And why? Ignore paint schemes if you can.
