ABOARD THE OBAMA EXPRESS (CNN) - The Amtrak train carrying President-elect Barack Obama and his entourage has left Philadelphia's 30th Street Station.
The 10-car, two-diesel-engine train is carrying 90 members of the media in addition to the President-elect, his family, his entourage and staff, and the Secret Service.
This is not a trip for the claustrophobic or anyone in a hurry. We will be covering 135 miles in approximately eight hours.
Upon boarding the train, most of the media headed for the café car.
As we pulled out of Philadelphia, about two dozen people lined a bridge to wave at the President-elect train as it departed Philadelphia.
