DeepSummary
The episode begins by explaining that railways predate the development of locomotives, with evidence of premade tracks dating back thousands of years before the first locomotive. It discusses the earliest known tracks, such as the post track in Somerset, England from 3838 BC, and the diolkos, an ancient overland shortcut for ships in Greece from the 6th century BC.
The transcript then traces the evolution of rails, from early wagonways used in mines in the 16th century, to the development of metal rails and flanged wheels in the 18th century. It covers the standardization of rail gauges, with George Stephenson's 1435 mm gauge becoming the global standard by 1845.
Finally, the episode looks at advancements in rail technology for high-speed rail, such as continuously welded rails, concrete ties, and banked curves. It mentions the potential for future magnetic levitation railways and emphasizes the enduring importance of rail transportation despite new forms of transportation.

- “Unbeknownst to most people, tracks and rails predated locomotives by centuries, although they were in limited use until the development of the steam engine.“ by Speaker A
- “Today, Stevenson's 1435 millimeter standard gauge is used by 70% of all the railways in the world.“ by Speaker A
- “Magnetic levitation railways propose to put electromagnets in rails to levitate above the track, resulting in zero friction. With zero friction, you could theoretically achieve speeds much higher than even the fastest trains.“ by Speaker A
- “Rail travel is still popular around the world today, and given some of the technology on the horizon, it will probably be around for centuries to come.“ by Speaker A
