The line graph illustrates the amount of railway track usage, measured in thousands of kilometres, in four countries – China, the USA, Russia, and India – over a 30-year period from 1980 to 2010.
Overall, different trends were observed. It is clear that the USA dominated with the highest use of railway tracks, while India recorded the lowest figures throughout the period.
Regarding the details, the USA experienced the highest use of railway tracks at 250,000 km in 1980. Although it decreased slightly to approximately 230,000 km in 2010, it remained dominant over the other countries. Meanwhile, the length of railway tracks in Russia stood at 150,000 km in 1980, before declining to around 130,000 km in 2010.
Turning to the lower-ranking countries, China and India followed lower trajectories. Initially, China had the lowest figure at around 20,000 km, but it rose dramatically to nearly 90,000 km by the end of the period. The length of railway tracks in India was around 30,000 km in 1980. Despite increasing significantly to approximately 70,000 km in 2010, it still could not surpass China.
