The graph presents the data about the number of people who traveled by train in Great Britain from 1950 to 2004/5.
In 1950, 1 billion citizens commuted through the National railway network before it gradually decreased and hit a low of nearly 600 million in the early 80s. However, from the 1980s to the early 2000s, there was a notable surge in passenger journeys, peaking at around 1.1 billion in 2004/5. By contrast, London Underground travel has been roughly stable for about 25 years. During the 1990s, the London Underground saw a significant increase in passenger numbers, reaching a peak of around 1 billion in 2004/5.
On the other hand, the Light Rail and Metro systems recorded the lowest number of passengers and began operations in 1965, with 10 million passengers. However, between 1980 and 2004/5, passenger numbers on these systems increased significantly, reaching almost 200 million in 2004/5.
Overall, the trend for all three networks is upward, with the National Rail network and the London Underground showing the most significant growth
