Using this bridge is easy. Just place it on your model railroad layout where you want it. Make sure the base is flat and stable for a proper fit. When handling, hold it gently to avoid any damage. To keep it in good shape, avoid touching it with dirty hands as it can cause tarnishing. You can use a soft, dry cloth to clean it occasionally. Keep it in a dry place away from direct sunlight to prevent any discoloration. If you notice any loose parts, use the included spare parts to replace them. Enjoy adding this beautiful bridge to your model railroad!
