The use of the same basic sizes of containers across the globe has lessened the problems caused by incompatible rail gauge sizes in different countries. The majority of the rail networks in the world operate on a gauge track known as standard gauge, but many countries (such as Russia, India, Finland, and Lithuania) use broader gauges, while many others in Africa and South America use narrower gauges on their networks. The use of container trains in all these countries makes transshipment between different trains of different gauges easier.
