Abstract
A universal boxcar is provided with load carrying capabilities of a conventional uninsulated boxcar and temperature ratings of an insulated boxcar. The insulated boxcar may be formed with interior dimensions corresponding generally with interior dimensions of an uninsulated boxcar without requiring the use of high cost, high performance insulation. The insulated boxcar may be formed at a reasonable cost and selling price with increased load carrying capacity, increased service life, and reduced maintenance costs as compared to conventional insulated boxcars.
