According to a report published by SCI Verkehr, Germany, all types of rail traffic are expected to grow up to 2025. Urban rail is due to grow at an average of 5% per year, but will slow after 2020 due to increased competition with many metro and light rail projects currently under construction. Mainline passenger numbers show vastly different regional trends with traffic falling in Eastern Europe, the former Soviet Union, Africa and the Middle East, but continuing to grow rapidly in Asia and South and Central America.
