Using this tender is easy. Just connect it to the appropriate Santa Fe 2 - 10 - 4 or 2900 Class 4 - 8 - 4 locomotive. When handling, be gentle as it's a fragile brass model. For storage, keep it in the original box and hand - cut foam to prevent damage. Clean it gently with a soft cloth to remove any dust. If you notice more tarnish over time, you can use a mild brass cleaner, but test it on a small, hidden area first. Remember, it doesn't have couplers, so you'll need to add them if you want to couple it to other cars. And if you're not satisfied with your purchase, let us know within 30 days for a hassle - free return, just pay the return shipping (unless the item arrived damaged).
