Actually a slightly pre-CSX experimental paint scheme.
L&N acquired only four U28Cs. They were later upgraded to 3000HP and fortunately looked unchanged.
From ACL to SCL to SBD this unit has lately been reduced to yard service but this got it a fresh paint job. You can still smell the Imron.
This was a good catch when they came out with their deucedly clever new "image". I guess my memory must have failed me but I thought I saw this in Clifton Forge in 1970.
