The provided line chart illustrates the changes in the amount of goods transported by four different modes of transport in the United Kingdom from 1974 to 2002. The modes included are road, water, rail, and pipeline, and the quantities are measured in million tonnes.
Notably, all modes of transport experienced upward trends except for rail, which remained essentially unchanged over the twenty-eight-year period.
In 1974, the quantity of goods transported by road stood at approximately 70 million tonnes. This figure fluctuated between 1974 and 2002, reaching a peak of just below 100 million tonnes, making it the highest among all modes by the end of the period. In contrast, pipeline transport had the lowest initial quantity, at around 5 million tonnes in 1974. It increased substantially over the following twenty years to above 20 million tonnes, then stagnated at this level until 2002.
Additionally, both water and rail transported around 40 million tonnes of goods in 1974. Although water transport experienced some stagnation in the early years, it began to rise steadily from 1978, reaching above 60 million tonnes by 2002. On the other hand, rail transport saw minor fluctuations but remained around 40 million tonnes throughout the period, ultimately slightly declining.
Overall, the quantities of goods transported by road, water, and pipeline increased significantly, while rail transport remained relatively unchanged despite several fluctuations.
