High-Speed Rail
A high-speed rail service can deliver competitive advantage over airlines for journeys of up to about 3 hours or 750 km, particularly between city pairs where airports are located far from city centres. One suitable type of corridor is that which connects two large cities 250-500 km apart. But another promising situation is a longer corridor that has very large urban centres located, say, every 150-300 km apart. On these longer corridors, typical of some being built in China, high-speed rail has the ability to serve multiple city-pairs, both direct and overlapping.
