This morning I actually trued to alias the C39-8 shape file that i've been working on in the Unreal Engine for the AC4400. Because of some incorrect materials in the cab the unit showed up invisible, but it is an encouraging sign that this can be done. It's not a substitute for buiilding a locomotive in from source, but hey, baby steps!
