After the UP merger of 1996, quite a few SP GP40-2s soldiered on still in their original colors. To quickly re-number them into the UP locomotive numbering system, a simple yellow patch was applied to show off itâs new owner. As most units received a full coat of UP Armor yellow and Harbor Mist grey, a few managed to escape the repainting still showing the original ownerâs markings, albeit with faded colors well into the 2010s.
