We're taking our first trip on the Coast Starlight in a few weeks, and have a novice Upper Level Bedroom question re luggage. Does anyone have a link to the dimensions of what will fit in the compartment (as opposed to luggage racks on the lower level)? We're particularly interested in storage space beneath the lower bed (couch). Our carry-on bags generally fit easily into airplane overhead compartments, but I suspect that may not be useful planning information; having the specific measurements for the Superliner storage shelf above the seating area and the floor under the lower bed would be extremely helpful.

TIA!
