Dutch Train NS Trein 1 to 500 Free 3D print model

I've converted a Dutch train model from an STL file into an SLDPRT design. The original SketchUp file was obtained from Google's 3D Warehouse under the identifier ffef9751ec79f8bca097e7ac87bcdb34, with various corrections made along the way. I then scaled down the object to represent it in a 1:500 scale but had some difficulty eliminating hollow spaces surrounding the wheels as well as very thin walls within certain sections of the train's design. As a result, the model may be unprintable without additional refinement or fixing these errors by someone familiar with SolidWorks design.
