The given line graph illustrates the statistics of journeys made by commuting on railway in the UK excluding northern Ireland from 1950 to 2004/05.
Overall, the most recent method of railway travelling is the light rail and metro systems, which was introduced in around 1963 and also the least popular means of transport. In addition, the figures of all categories experienced an upturn, with London Underground having the most significant change and the two remaining methods’ noteworthy volatility.
In 1950, exactly one billion journeys were made by passengers using national rail network, compared to about 730 million of those on London’s subway system. After 54-55 years, the former oscillated heavily before a moderate increase to reach a peak of roughly 1.1 billion by 1960, followed by a plunge to sink a trough of around 600 million in the early 1980s preceding the profound ỉmprovement close to the initial milestone in 2004/05. Simultaneously, having variably and gradually decelerated to approximately 500 million in the early 1980s, the latter later observed an upsurge of about 600 million in 2004/05.
During the introduction of lightrail and metro systems around 1963, there were about 10 million journeys made by commuting via these systems. Afterwards, the number of journeys on light rail and metro systems diminished to almost zero in 1980 before a oscilating upward change to abou 230 million journeys on these systems in 2004/05.
