Alternative railway futures: growth and/or specialisation?

Abstract

Recent centuries have seen a succession of transport technologies, each offering improvements in speed, carrying capacity and/or operational flexibility. Having overcome many physical barriers to freedom of movement, humanity now faces two major, related challenges: dwindling reserves of fossil fuels, and anthropogenic climate change. In these circumstances, rail transport has significant potential advantages over the more energy-intensive modes of road and air.Railways dominated 19th century land transport, peaking in importance in the early 1900s. Market share then declined in the face of competition from road transport and aviation, although rail retained significant passenger and freight transport roles. Major improvements in railway operating efficiency were introduced later in the 20th century, including: the switch from steam to diesel and electric traction; containerisation and focus on long-haul, unit-train freight operations; and the development of high-speed passenger rail services in Japan and Europe, enabling rail to compete successfully with air travel over distances of up to 800km.The UK Government’s Foresight Programme commissioned a report entitled Intelligent Infrastructure Futures, for which four scenarios were developed of how society might be in 2055. These scenarios are: ‘Perpetual Motion’, ‘Urban Colonies’, ‘Tribal Trading’ and ‘Good Intentions’, each having its own implications for the future of transport. This paper considers the implications of each scenario, and of the underlying/overriding issues of peak oil and climate change, for the possible role and significance of rail transport in meeting our transport needs in the mid-21st century and beyond.
