Renfe AVE high-speed trains - copyright Paul Langan An Educational Guide for Canadians on the Evolution of Railway Track Technology One of the mandates of High-Speed Rail Canada is to educate Canadians on high-speed rail.  I have been at several high-speed rail symposiums and always found the Infrastructure sections of them interesting.  The ALTO/Cadence high-speed rail project between Ontario-Quebec, offers for the 1st time in Canada, true high-speed rail. But what exactly will that look like and what technology will they use? I have been on a number of different high-speed rail trains operators in Europe and have looked at different systems around the world. With ALTO suggesting speed of over 300 km/h in sections, the question of what type of ballast system they will use is just one of many that need to be clarified. As Canada explores expanding its passenger rail network and considers high-speed rail corridors, understanding the fundamental technologies that make mo...
