Final answer:
Railroads can carry a significant amount of freight and are relatively low cost. They are good for transporting heavy, bulky items, but may not be the fastest option.
Step-by-step explanation:
Railroads can carry a significant amount of freight compared to other forms of transportation. Due to their extensive network of tracks, railroads are able to transport large volumes of goods efficiently and economically. They are particularly good for transporting heavy, bulky items such as coal, steel, and raw materials. Railroads also have the advantage of being relatively low cost, as they require less fuel compared to trucks or airplanes. However, rail transportation tends to be slower compared to air or truck transportation, so it may not be the best option for time-sensitive deliveries.
