Note: oregon electric special
so is railway grade
Curator Response: Thanks for the report. Electric railways are not considered in qualification for "Railroad Grade." Grade 926 was not adjusted to positions, and would not have been accepted into service on American railroads at the time. The "Oregon Electric Special" private label has been noted in the information above.
