Better yet, here is a link to train luggage on Etsy, you could mix and match and they are inexpensive! Really cool :)

Hi Linny, if you want the real deal, I would recommend looking on eBay, they have quite a few, although the price varies. Are you looking for suitcases specifically or trunks? also what are the colors and dimensions? Let me know, would love to help!
