National Train Day is observed annually on the Saturday closest to May 10, with the 2026 celebration falling on May 9. This holiday was initiated by Amtrak to raise awareness about the history and benefits of railway networks in the United States, emphasizing the eco-friendly nature of train travel. It commemorates the establishment of the Golden Spike in Promontory, Utah, marking the completion of the first transcontinental railroad. Typical customs include organizing exhibitions of railroad layouts and promoting the use of trains for both passenger and freight transport. Amtrak provides railroad services across numerous cities in the U.S. and three in Canada, highlighting the significant role of trains in modern transportation.
