I have a Tyco/Mantua Dupont Chemical Tank Car I purchased off of Ebay a couple years ago. It came with Baker Talgo Couplers that I replaced with body mounted Kadee #5s. It made a good addition to my roster. In fact, I have a few Tyco/Mantua cars in my roster. They lack detail; but, with the judicious addition of details and weathering, make very nice freight cars!
