Using this model is quite simple. Just make sure it's on a proper track, and you can let it run. Since it has smooth operation, it should move nicely along the track. When handling the model, be gentle as it's a fragile item, especially being a brass model. For maintenance, regularly check the wheels for any debris that might affect its smooth running. You can use a soft, dry cloth to clean the exterior and keep it looking its best. If you have any issues with the sound on the tender, refer to the spare parts that came with it. When it comes to shipping, if you're getting it internationally, be aware that you'll be responsible for any import - related costs. And if you're not satisfied with your purchase, you have 30 days to get a refund, but remember you'll pay for return shipping unless the item arrives damaged.
