These are the magnetic couplers. I have a basic bachmann set with regular plastic couplers. I am interested in buying a Penn Central Loco. I see that Atlas makes a Penn Central Loco the 630 that comes with accumate knuckle couplers that are magnetic? I have a bachmann track that connects easily it's on a plastic base, and my box cars and so on are regular plastic couplers. How do I make things compatible? Can I use that Atlas loco with regular plastic couplers? If not how do I make things compatible.
