PRR X31A Boxcar Stud Developer™ Printed Instruction Set
About the Model
In the middle of the depression in 1934, the Pennsylvania Railroad began a massive car building program in its Altoona, PA shops. The round roof design was adopted to achieve the maximum cubic foot capacity loading and still clear tunnel restrictions. The X31 series became their new and distinctive standard box car. Two basic roofs were adopted - one flush to the sides and the other with a 2” setback at the top of the roof. Cars were both 40’ in length and came with either single or double doors with 6' and 12’-1-1/2” or 14‘-6” openings respectively. During one period between March and April 1936, many of these cars were contracted out between builder’s AC&F, BSC, GATC, GSC and PSC. In 1939 and through 1940, the PRR modified the roofs of 690, 40’ double-door cars with a distinctive extended roof to accommodate jeep shipments. These were designated as X31F and classified XAR.
