摘要

In the two years that have passed since our last survey, the world’s high speed networks have continued to grow apace. However, dedicated high speed lines are still largely limited to Europe and the Far East. In today’s terms, there are no services that could really be regarded as 'high speed' in the Americas, South Asia, Africa or Australasia. In all of these regions, the conventional view has been that the distances between major population centres are too great for rail to compete with air, although recent developments suggest that the Chinese may be rewriting the rules, offering journey times of 8 h or more and operating high speed trains with sleeping cars on the longest routes.'
