===Gauge incompatibility===
{{Main|Break of gauge}}
The use of different [[track gauge]]s in different regions of the world, and sometimes within the same country, can impede the movement of passengers and freight. Often elaborate transfer mechanisms are installed where two lines of different gauge meet to facilitate movement across the [[break of gauge]]. Countries with multiple gauges in use, such as [[Project Unigauge|India]] and [[Rail gauge in Australia|Australia]], have invested heavily to unify their rail networks. China is developing a modernized [[Eurasian Land Bridge]] to move goods by rail to Western Europe.
