"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. The STEM of High-Speed Trains 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 new advances like maglev trains that use magnets to levitate"--.
