A boxcar and load restraint system are provided with improved load carrying capabilities and performance characteristics of uninsulated boxcars and insulated boxcars. An insulated boxcar with the load restraint system may have increased load carrying capacity, increased service life, and reduced maintenance costs as compared to conventional insulated boxcars. All or portions of the load restraint system may be used in uninsulated boxcars.

The boxcar of claim 1 comprising: an exterior surface of each sidewall assembly formed in part by layers of fiber reinforced plastic material; an interior surface of each sidewall assembly formed in part by metal sheets; and insulating materials disposed between and bonded with the layers of fiber reinforced plastic material and the metal sheets. 4. The boxcar of claim 1 comprising: an exterior surface of each sidewall assembly formed in part by metal sheets; an interior surface of each sidewall assembly formed in part by layers of fiber reinforced plastic material; and insulating materials disposed between and bonded with the layers of fiber reinforced plastic material and the metal sheets. 5. The boxcar of claim 1 further comprising: an exterior surface of each sidewall assembly formed in part by a plurality of metal sheets; an interior surface of each sidewall assembly formed in part by a plurality of metal sheets; and insulating materials disposed between and bonded with the metal sheets forming the exterior surface and the metal sheets forming the interior surface. 6. The boxcar of claim 1 further comprising: insulating material disposed between the interior surface and the exterior surface of each sidewall assembly; and the boxcar selected from the group consisting of a temperature controlled railway car and an insulated boxcar. 7. The boxcar of claim 1 further comprising the box structure satisfactory for carrying lading selected from the group consisting of coiled steel, lumber, pasteurized and unpasteurized beer, wine, newsprint, paper rolls, automobile parts, household goods, perishable food products and non perishable. 8. A boxcar comprising: a box structure defined in part by a pair of sidewall assemblies, a pair of endwall assemblies, a floor assembly and a roof assembly; the floor assembly mounted on a railway car underframe; the sidewall assemblies mounted on the railway car underframe adjacent to opposite sides of the floor assembly; a respective longitudinal joint formed between each sidewall assembly and adjacent portions of the floor assembly; each sidewall assembly having an exterior surface and an interior surface; a plurality of support posts disposed between the interior surface and the exterior surface of each sidewall assembly; portions of a cargo restraining system disposed within each sidewall assembly proximate the respective longitudinal joint with the floor assembly; respective angles extending longitudinally along opposite sides of the floor assembly; each angle disposed adjacent to and securely engaged with one of the sidewall assemblies proximate the respective longitudinal joint between the sidewall assembly and the floor assembly; a plurality of openings formed in each angle; the openings sized to receive cargo anchor assemblies; generally U shaped channels disposed within each sidewall assembly adjacent to the openings in the respective angle; and the generally U-shaped channels cooperating with each other to prevent fluids used to clean the floor assembly from contaminating insulating materials disposed within the respective wall assembly. 9. A boxcar comprising: a box structure defined in part by a pair of sidewall assemblies, a pair of endwall assemblies, a floor assembly and a roof assembly; the floor assembly mounted on a railway car underframe; the sidewall assemblies mounted on the railway car underframe adjacent to opposite sides of the floor assembly; a respective longitudinal joint formed between each sidewall assembly and adjacent portions of the floor assembly; each sidewall assembly having an exterior surface and an interior surface; a plurality of support posts disposed between the interior surface and the exterior surface of each sidewall assembly; portions of a cargo restraining system disposed within each sidewall assembly proximate the respective longitudinal joint with the floor assembly; each support post having an I beam cross section; a respective backup plate attached to the first surface of each support post; thermal insulating material attached to the backup plates opposite from the associated support port; a generally U shaped channel disposed between the thermal insulating material and the interior surface of the associated sidewall assembly; and each pocket disposed in one of the U-shaped channels. 10. A boxcar comprising: a box structure defined in part by a pair of sidewall assemblies, a pair of endwall assemblies, a floor assembly and a roof assembly; the floor assembly mounted on a railway car underframe; the sidewall assemblies mounted on the railway car underframe adjacent to opposite sides of the floor assembly; a respective longitudinal joint formed between each sidewall assembly and adjacent portions of the floor assembly; each sidewall assembly having an exterior surface and an interior surface; a plurality of support posts disposed between the interior surface and the exterior surface of each sidewall assembly; a plurality of pockets formed within the interior surface of each sidewall assembly; each pocket disposed adjacent to one of the support posts; a cargo anchor disposed within each pocket and securely engaged with the respective sidewall assembly; portions of a cargo restraining system disposed within each sidewall assembly proximate the respective longitudinal joint with the floor assembly; each support post having an I beam cross section; a respective backup plate attached to a first surface of each support post; thermal insulating material attached to the backup plates opposite from the associated support port; a generally U shaped channel disposed between the thermal insulating material and the interior surface of the associated sidewall assembly; and each pocket disposed in one of the U-shaped channels. 11. The boxcar of claim 10 further comprising the box structure satisfactory for carrying lading selected from the group consisting of coiled steel, lumber, pasteurized and unpasteurized beer, wine, newsprint, paper rolls, automobile parts, household goods, perishable food products and non perishable. 12. An insulated boxcar comprising: a box structure defined in part by pair of sidewall assemblies, a pair of endwall assemblies, a floor assembly and a roof assembly; the floor assembly mounted on a railway car underframe; the sidewall assemblies mounted on the railway car underframe adjacent to opposite sides of the floor assembly; each sidewall assembly having an interior surface and an exterior surface with insulating materials disposed therebetween; a plurality of support posts disposed between the interior surface and the exterior surface of each sidewall assembly; a plurality of pockets formed within the interior surface of each sidewall assembly; each pocket disposed adjacent to one of the support posts; a cargo anchor disposed within each pocket and securely engaged with the respective sidewall assembly; respective anchor restraints extending longitudinally along opposite sides of the floor assembly; each anchor restraint disposed adjacent to one of the sidewall assemblies proximate a respective longitudinal joint formed between the sidewall assembly and the floor assembly; a respective backup plate attached with a first surface of at least one support post and thermal isolating material attached with the backup plate opposite from the support post; and a generally C-shaped channels respectively disposed adjacent to the thermal isolating material opposite from the backup plate. 13.
