Garrett,
here's an autocar facility in southeastern PA just near the DE/PA line. Perhaps the design of this can give you a centerpiece to design around. This facility is busy, so it will certainly give your trains something to do or have a reason for being. NS services this.
It's Google maps, so you can zoom and switch from satellite to maps and such. You can see there are three locations where the spurs are paved for simultaneous loading/unloading activities.
I would definitely look cool with foam or raised Masonite to rail level.
I just can't figure out how to get tighter spur spacing with FasTrack. Hmmmnn...
