The first successful United States Pony Express run from St. Joseph, Missouri, to Sacramento, California, begins.

The inaugural Pony Express mail service departs on April 3, 1860, embarking on a 1,900-mile horseback journey across the American frontier.
The Pony Express dramatically reduced communication time between the East and West Coasts of the United States. Riders relayed mail on fast ponies through a network of stations spanning Missouri to California. Each rider covered approximately 75 to 100 miles per shift, changing horses at relay posts. Though operational for only 18 months, the service captured the public imagination and symbolized the ingenuity and daring of the American West. It paved the way for future advancements in transcontinental communication, including the telegraph.

Conventional-Train World Speed Record: A French TGV train on the LGV Est high speed line sets an official new world speed record of 574.8 km/h (159.6 m/s, 357.2 mph).

On April 3, 2007, a French TGV train on the LGV Est line set a new world speed record of 574.8 km/h.
On April 3, 2007, the French TGV experimental train achieved an official world speed record of 574.8 km/h on the LGV Est high-speed line. This feat surpassed all previous rail speed records and demonstrated the advanced capabilities of high-speed rail technology. Engineers fine-tuned aerodynamics, braking systems, and track conditions to safely sustain such unprecedented velocity. The achievement highlighted France’s leadership in railway innovation and spurred global interest in ultra-fast rail travel. Although conducted under controlled conditions, this milestone showcased future possibilities for reducing intercity travel times. Subsequent high-speed rail development drew lessons from this record-setting run to enhance performance and safety.
