National Train Day is a holiday started by Amtrak in 2008 as a method to spread information to the general public about the advantages of rail travel and the history of trains in the United States. It is held each year on the Saturday closest to May 10, the anniversary of the pounding of the Golden spike in Promontory, Utah which marked the completion of the first transcontinental railroad within the United States. Events are held at Amtrak stations as well as railroad museums across the country and often have passenger cars and model railroad layouts on display. The largest events usually take place in Washington, D.C., Philadelphia, PA, Chicago, IL, and Los Angeles, CA.
The National Association of Railroad Passengers, the largest non-profit rail advocacy organization in America, announced that their members would be celebrating the first National Train Day in 2008.Many other non-profits participated regionally.
In 2015, it was announced that the community program called National Train Day would be replaced by a company sponsored event called Amtrak Train Days. The format changed from multiple events on a single day in many cities to individual events over the course of the spring, summer and autumn.
