High-speed rail is an evolving phenomenon that began in Japan many years ago and was then developed in Europe, initially in France, then in Germany and Spain, now Italy, connecting to places in Belgium and the U.K. through the Chunnel.

I think the study needs to look carefully in that regard at the objectives in terms of transportation choices, but also the outcomes in terms of the distances that people travel, that they need to travel or are indeed encouraged to travel. Where is the balance, if you will, from a sustainable perspective, between people travelling together in a sustainable electric mode, people travelling long distances, as opposed to locating things closer together and not needing to travel as much? In other words, there are two sides to the coin in terms of the benefits and disbenefits of a particular investment.
