I noted with interest that Atlas has announced N scale models of USRA boxcars, originally wood sheathed rebuilt with steel sides, including Texas and Pacific numbers 80282,81142 Texas & Pacific My 1954 EqpReg lists 80000-80553; 81000-81425 779 cars. 1971 EqpReg p.695-701 7 cars surviving within this number series. I shot a picture of what appears to be a USRA rebuild-- some 30 years ago, immobilized at Corpus Christi as a storage shed.
