Abstract
Insulative panels mountable to the exterior of a railway boxcar, and railway boxcars having exterior insulative panels are disclosed. Each disclosed insulative panel may have first and second skins of fiber-reinforced plastic spaced apart from each other with foam or other insulative material interposed into the space therebetween. The disclosed insulative panels can be attached to the exterior of an existing, non-insulated boxcar to retrofit it as an insulated boxcar. In addition, thermally insulative material may be positioned vertically above a door opening for additional insulation.
