Are there any MOPAC units left in the UP Armour yellow scheme?
If you mean units with “MISSOURI PACIFIC” spelled out on the hood of the otherwise UP scheme, unfortunately they have all been repainted. However, there are many ex-Mopac engines now serving in UP paint.
Yes, those are the ones I were talking about.
A good number of the C36-7’s (ex-MP 9000’s) were rebuilt and re-gauged and are now serving on the privatized Estonian Railways in Wisconsin Central colors.
