I'm getting more and more used to working with these really tiny parts. This is a metal kit. It takes some time to properly clear the flash left over from casting. This is ABSOLUTELY necessary because it's a metal kit and will not fit together properly if you don't smooth it out. Before assembling, (or during,) consider your painting scheme and paint the model as you go. Some parts will be impossible to get to once assembled, (the seat in the cab for example.) All in all a good fit for an n-scale layout with a mine.
