Please note: Atlas "O" scale couplers can also be used on both 2-rail and 3-rail versions.
Atlas O’s 50' PS-1 Box Car represents a classic American freight car from the 1950s and 1960s, when fifty-foot box cars became the standard. Many railroads of the period operated Pullman Standard's box cars, but details were often specific to each company. One of details that differed was the supplier of the doors (Youngstown or Pullman Standard styles).
