Amtrak baggage car

I’ve recently taken a small interest in passenger equipment. My present layout is way too small to ever handle full length Superliners, but I’ve decided I can live with a shelf queen on the mantle. It seemed logical to duplicate the train I use the most: the Capitol Limited. The only sticking point I have is what they’re using for baggage cars these days. I’m an absolute novice at this, so I don’t know the differences between passenger cars other than the basics (like I know that they’re not heavyweights). Who’s baggage cars would be the best for this purpose?

I use something like this for mine.
