Using this tender model is straightforward. Just connect it to your compatible New Haven Class R - 3a 4 - 8 - 2 locomotive with the installed Kadee coupler. When handling it, be gentle as it's a fragile brass model. To maintain its great appearance, avoid exposing it to extreme temperatures and humidity. Clean it gently with a soft, dry cloth to keep the custom paint and decals in good shape. Store it in the provided box when not in use to protect it from dust and potential damage. If you notice any issues during use, don't hesitate to contact us.
