This set was produced to introduce an more comprehensive set for these classes.
Beginning in 1909, the PRR introduced the H21 class of hoppers; by 1951 the class had peaked with a mammoth count of 39,699 cars. Known for its longevity in the fleet, this car became a signature of the Pennsy’s coal trains. This class of car was rebuilt many times throughout the years. Notable classes wearing the Circle Keystone scheme were H21a, H21b, and H21e.
Some of these cars lasted to the end of the PRR in 1968. However, most were scrapped by Conrail.
The H21 subclasses were in many different numbering blocks, with no discernible documentation of what numbers were assigned to each class, instead only total fleet numbers given.
The two 12 car number sets contain correct numbers for doing 4 H21A/H21B/H21E, 6 H21A/H21B, and 2 H21A. The one 6 car set contains correct numbers for doing 6 H21A/H21B/H21E. There are six different reweigh/repack dates cover locations system wide and multiple re-weigh dates ranging from the mid 1930’s through to the late 1950’s.
Careful Analysis of the numbers provided has revealed that by combining all three decal sets you can get over 250 correct car numbers by mixing and matching car prefix numbers.
The H21 class has been produced in plastic by Bowser and resin by Westerfield.
