The April issue of Trains magazine has a special 48 page report on fast trains. It describes new high-speed trains in China, Korea, Taiwan, Japan and Europe, relative speed, why some Americans can’t seem to embrace high-speed rail, a map showing the highest speed portions of tracks in the USA (70 mph (112 km/h) is considered high-speed for Amtrak) and many other articles.
A special article on Amtrak Cascades describes how Washington state has grown their system slowly and steadily over the past 10 years by focusing on small incremental improvements to increase the average speed over time, instead of trying to focus on top speeds. It is frequency, reliability and comfort that will bring people back to the train, not absolute top speed. This article especially should be required reading for folks at the BC Ministry of Transportation who are overly focused on roads.
