Trainz is not very prototypical unless you do a lot of your own session creation. A lot of the rolling stock and industries are designed to "load" and "unload" instantly before your eyes. It seems that people enjoy seeing a cut of boxcars all load/unloaod at the same time. Anyway... once you learn how to drive and do basic operations start learning about session creation and just do your own thing however you wish. Also, if you truly want prototypical ops emphasized over graphics send me a private msg (conversation). There's an alternative sim you might me interested in if you don't already have it or know about it.
