Corporate travelers in the Northeast Corridor are hopping the train these days — almost more than they're flying on shuttles.

Amtrak's Acela Express is competing neck-and-neck with some airline shuttles as travelers take advantage of the train's convenience and amenities, such as electrical outlets for laptop computers and cell phones, and tables stationed throughout the train. The Acela provides service between Boston and Washington, D.C., with stops in Providence, R.I.; New York; Newark, N.J.; Philadelphia; and Baltimore.

Some companies are even starting to see the train as an easy, on-the-go meeting venue.

“We've had a lot of interest from companies about holding meetings on board the train,” says Karen Dunn, Amtrak spokeswoman. “It's a new market for us, and we're just beginning to tap into it.”
