If you really want to get "real" then utilize a switchback to gain elevation. That would work well with an 0-4-0 and a few cars. The odd thing would be seeing that type of engine going up a hill in a mining/logging fashion.
When deciding between prototypical and other factors, I tend to side on "looks good" instead of "prototypical" because looks good can look real if done well.
