Out of the blue, Amtrak has decided to allow Americans in on the big rail pass scheme that's usually offered only to international visitors. We don't know why (we don't even know when Amtrak will arrive at the station, so how could we know about its business practices?), but the loosening of the rules can translate into some hefty savings off the usual rates. Just in time, too, for car-weary budgets.

Up to now, the USA Rail Pass was only offered to visitors from abroad. Americans who wanted the discount found themselves out of luck, so most of us didn't know much about it.

The USA Rail Pass works a lot like the more famous Eurail passes. It's good for a defined length of time (it comes in 15-day/$389, 30-day/$579, and 45-day/$749 varieties) and you can take a set number of trips during that period (8 for 15 days, 12 for 30, and $18 in 45 days).

The pass can be used both on trains and on the connecting Amtrak Thruway bus system. It can also be used anytime as long as you start using it within six months of buying it. There are a few notable exceptions, though. You can't use it for the swishy Acela service in the Northeast (although you can use it for regular train service serving the same cities), and the Auto Train to or from Florida (on which you also bring your car) is also out.

There's something romantic about train travel. Is it the memories of the model train running on tracks around the Christmas tree, the luminous artwork in "The Polar Express"? The clips from old movies of the rich and fashionable strolling down the platform, carrying luggage in a gloved hand?

Maybe it's the names of the trains. The Silver Meteor which has run from New York to Miami since 1939. then there's The Cascades, The Adirondacker, The Heartland Flyer.

The sound of the wheels on the tracks, the blur as the country slides by outside the window of the dining car, has universal appeal. Train trinkets abound: On May 9th, there were 90,081 listings under "trains" on eBay, 12,109 under "railroad," with more bids than one might expect in the current economy.

But train travel is more than just a novelty. It is econ-friendly, for starters. Then there are more sights accessible by rail in the U.S. than most of us might assume - including the Grand Canyon, Niagara Falls, Yellowstone Park, and Disney World. The last full service railroad in the U.S. is the Alaska Railroad (http//alaskarailroad.com/arrc53.html) which offers special events including a beer train.

An Amtrak North America Railpass allows unlimited stops to over 900 destinations in both the U.S. AND Canada and is valid for up to 30 consecutive days. As gas prices rise and air travel gets more arduous, this may be just the ticket.

Think of all the forms of transportation Americans once depended upon. Which would you like to see return?
