Code. (My copy of the April 1961 ORER does not have this column - my
copy of the 1/1967 does.)"
Okay... I'm going to try this again... Allen is referring to Great

Allen also asked...
" What other freight car code systems are there (besides AAR/ORER codes),

stenciling applied to the cars (near and below the load limit line) appears
much more frequently after 1961. Try asking on the GN list.
