SD40 were delivered in October '66, so it was at least by then.
Prior to that KCS and CGW basically had the same scheme correct?

The GP30's had almost identical schemes, but beyond that, not so much really. There's a family connection between the CGW and KCS as William Deramus III was president of the CGW from 1949-1957 while his dad was the KCS president from 1941-1961. Deramus III went to MKT for three years and then became president of KCS from 1961-1973.
