Why are railways considered better than trucks for carrying goods for longer distance?

Carrying goods for a longer distance with a train is better than conveying the goods with a truck because trains are meant to carry heavy loads. Also, there are some trains specially designed to carry only goods, not humans. It is also of note that carrying goods through railways is safer than through the road. The rate of accidents on the road is higher than that of railways. The cost constraint is also a reason to carry goods via railways than trucks because compared to refilling gas frequently which will be expensive, a train will consume less fuel.
