"The "50 States" journey officially begins on "Good Morning America" the week of Sept. 15 with (ABC newscasters) anchoring the morning broadcast onboard a specially equipped Amtrak train."
"The broadcast studio on the rails will consist of three locomotives and eight rail cars, two of which are historic antique cars. The "GMA Whistle-Stop Tour" will travel through seven states, making several stops along the way, as the show broadcasts live from four states and Washington, D.C., over five days. "
The most important car, however, is the 'cabenna car', a converted baggage car making the news transmission possible (check out video.)
"Good Morning America Weekend," "Nightline" and "World News With Charles Gibson" will also broadcast from the rails for the "50 States in 50 Days" tour.
ABCNews.com, "GMA Now" and USA Today will provide additional coverage of the historic event."
