On the Fast Track In 2017, the new 480-kilometre Mombasa-Nairobi railway was opened. Before then, the only transport links between Mombasa, Kenya’s main port, and Nairobi, Kenya’s capital, were rough roads and an old railway line completed in 1901. The old trains were very slow. It took 10 hours to get to Nairobi from Mombasa by train. 1b Look at the title and the picture. What is the text probably about? Then read it quickly to check your prediction.
