Due to the increasing installation of overhead electric wires on US railways it is not considered a safe procedure to load block ice into the roof compartment for the fridge. The chef had to make do with bagged ice cubes.
Above the fridge is the cigar humidor.

A humidor is any kind of box or room with constant humidity that is used to store cigars, cigarettes, or pipe tobacco. For private use, small wooden or acrylic glass humidor boxes for a few dozen cigars are used, while cigar shops may have walk-in humidors. Humidors can be used to store other goods for which a certain level of humidity is desirable; the Colorado Rockies Major League Baseball team stores game balls in a large humidor at their home stadium, Coors Field, to counteract the effects of Denver's high altitude and generally low humidity. Humidors of all sizes use hygrometers to keep track of the humidity levels
