Although most people are excited about the prospect of a seat or bedroom high on the upper level of Amtrak�s Superliner fleet, I specifically chose a lower level room for two reasons. First, the downstairs rooms are quieter because there is much less foot traffic passing by your door. All the inter-car traffic is upstairs. As well, the train�s natural rocking motion makes for a difficult time walking and most people tend to ricochet their way down the narrow hallways, bouncing off walls and doors with equal abandon. One sleeping car passenger complained that her arms were bruised after just one afternoon on the train. Additionally, being lower in the train car results in much less tilt motion than is experienced on the upper levels. Like a fulcrum point on a seesaw, the ride is smoother the lower you are.
