Not all of Amazon's goods ship by rail. Amazon is an online retail giant with a wide range of goods, including books, electronics, household goods, clothing, food, and more. It can deliver goods to consumers through different modes of transportation, including express delivery services. In addition, Amazon also provides logistics services, including warehousing, distribution, and after-sales services. Amazon has a large number of warehouses and distribution centers around the world, which can provide consumers with fast and reliable goods transportation services.

Of course, different goods may use different modes of transportation. For example, some large items (such as furniture, home appliances, etc.) may need to be transported by rail, while some fragile goods (such as glassware, food, etc.) may need to use other safer modes of transportation.

In short, Amazon will choose the best mode of transportation based on the type of goods and the destination.
