The Atlas Master N Scale 1932 ARA 40' Steel Boxcar is based on cars that hit the rails between beginning in 1932. A goal of the American Railway Association (ARA) in the early 1920s was to produce an all-steel boxcar that could be recognized as a standard by the member railroads. Although the original design presented in 1923 produced in excess of 60,000 cars, it wasn't until a new design was presented in 1932 that the member railroads gave their approval. After extensively testing five prototypes in 1933, over 14,500 cars were produced for 23 railroads throughout the following decade. This design soon evolved into the 1937, Modified 1937, and Postwar AAR boxcars. Although not the most popular design produced, numerically speaking, the 1932 ARA Standard boxcar is considered one of the most important designs in railroad history. Models feature roadname appropriate body details with several styles of car ends, doors and roofs available. Cars also come in accurate schemes with free-rolling trucks and magnetic knuckle couplers. 1932 ARA 40' Steel Boxcars are part of the extensive line of Atlas N Scale boxcars.
