The STEM of high-speed trains

"At top speeds of more than 250 miles per hour (400 kilometers per hour), high-speed trains are designed to carry passengers over long distances quickly and safely. [This book] explores how trains have evolved over time and describes how special tracks, powerful motors,and physics come together to get travelers where they want to go--fast. Readers are encouraged to think critically about how trains stay on their tracks, how high-speed trains handle extreme friction, and . . . advances like maglev trains that use magnets to levitate"--Provided by publisher.
