Train afficionados can get their fix Saturday, May 10th, by heading to a handful of national park sites that will be commemorating the train in some form or fashion. Hitching its wagon to Amtrak's decision to celebrate National Train Day on Saturday, the National Park Service has plans for a number of events at park sites from coast to coast.

Amtrak selected May 10 as National Train Day to honor the completion of the Transcontinental Railroad at Promontory Summit, Utah Territory, on May 10, 1869 – today’s Golden Spike National Historic Site. The event joined 1,776 miles of track laid by Union Pacific and Central Pacific railroads.

“National Train Day is the perfect time for us to launch ‘Railroad Connections’ on WebRangers, our very popular children’s web site,” says Park Service Director Mary A. Bomar. “Many children have never been on a train so we developed ‘Railroad Connections’ to provide the stories of the growth of national parks and the development of railroads.

"Children are going to have a lot of fun as they learn. Youngsters will learn to run a steam locomotive, decode telegraph messages and learn about national parks to solve train and national park mysteries,” says the director.

You say you don't live nearby any national park site with train connections? Then you and your WebRangers can learn about trains without leaving home by calling up "Railroad Connections" on the Internet. This Park Service-run site features videos made at Golden Spike National Historic Site and at Steamtown National Historic Site in Pennsylvania.

Since 1994, Amtrak and the National Park Service have promoted train travel to national parks. The Trails & Rails Partnership Program places park rangers and volunteers on trains to share park information and to point out natural and cultural highlights on several regional Amtrak routes across the country.

The largest National Park Service presence on Saturday will be at Union Station in Washington, D.C., with park rangers and volunteers from the Park Service's Trails & Rails Program as well as rangers from Greater Washington National Parks on hand to discuss trains. There will also be a special National Park Service booth for children that will include the world premiere launch and demonstration of ‘Railroad Connections’ on WebRangers, a program supported by the Best Buy Children’s Foundation through the National Park Foundation.
