These PS-2 70 ton 2-Bay covered hoppers are painted Chessie Signal Yellow and display the large "Ches-C" herald in blue. They run on black roller bearing trucks. Built by Pullman Standard in 1968, the series 604100-604199 had 2700 cu. ft. capacities and were delivered in gray with the black B&O Capitol Dome herald. Cars of the HC-25 class were serviced in 1985 and re-painted in the Chessie System yellow/blue scheme on an "as shopped" basis; there were variations in how the scheme was applied. Here the "Ches-C" herald is stenciled in the center of the wide center panel. This scheme also includes the use of the "Keep Safety Rolling" slogan.
