May 9th
National Train Day

National Train Day was a holiday started by Amtrak in 2008 as a method to spread information to the general public about the advantages of railway travel and the history of trains in the United States. It was 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 in the U.S.
