STEM of High-Speed Trains 

At top speeds of more than 250 miles per hour, high-speed trains are designed to carry passengers over long distances quickly and safely. Readers will explore how trains have evolved over time and how special tracks, powerful motors, and physics come together to get travelers where they want to go. Readers are encouraged to think critically about how trains stay on their tracks and how high-speed trains handle extreme friction. They’ll be enthralled to learn about new advances like maglev trains, which use magnets to levitate.
