Amtrak bills the Cardinal's route as one of the most scenic in its system. After an early morning departure from New York and traveling south down the Northeast Corridor, the train passes through Virginia's rolling horse country, across the Blue Ridge and the Shenandoah Valley. Then the train climbs the Allegheny Mountains and stops at the resort town of White Sulphur Springs, home to The Greenbrier, a famous luxury resort. The Cardinal descends on tracks through the New River Gorge National River, a unit of the National Park Service protecting the longest deepest river gorge in the Eastern U.S. The river is popular for white water rafting, and the cliffs attract rock climbers. The forests blaze with autumn foliage and the train usually sells out during the peak season. The Cardinal will often add the only remaining full-length dome car in Amtrak service, car number 10031, to the consist in the autumn to try to accommodate the leaf peepers.
