A rail system comprises: a guide rail; a plurality of stationary electromagnets mounted in the guide rail; and a carriage having a plurality of wheels configured to travel along the guide rail. The wheels are magnets. Movement of the carriage along the guide rail is brought about by a fluctuating magnetic field generated by the stationary electromagnets acting on the wheels.

Example insulated pliable door panels or curtains include various internal vapor barriers. The vapor barriers have a relatively high water vapor transmission rate that inhibits water vapor from permeating through the door panel. With such vapor barriers, outer sheets of the door panel can be made of polyurethane or other tough materials that might have an inadequate water vapor transmission rate. In some examples, the vapor barrier encircles or encloses a thermally insulating pad. In some examples, the door panel includes a sleeve or pocket that holds the vapor barrier in place. Some examples include means for draining water that might condense within the door panel.
