If you want to try something different, I know at least two US railroads painted a diesel locomotive up in desert camouflage in 1991 to honor employees who were reservists called up for Desert Storm.
Canada did this in 2019
CALGARY, Nov. 12, 2019 /PRNewswire/ - Canadian Pacific (CP) unveiled five specially painted locomotives on Remembrance Day in Canada and Veterans Day in the U.S. honouring the culture and history of the armed forces. The five Electro-Motive Diesel SD70ACUs will take the message of military pride across the CP system.
CP personnel carefully studied the paint colours and patterns that branches of the Canadian and U.S. militaries applied to tanks, planes and warships. Based on their research, they devised five liveries for these locomotives:
CP 7020 wears North Atlantic Treaty Organization green, which the Canadian and U.S. armies apply to fighting vehicles and equipment serving in temperate climates.
CP 7021 wears the sand colour that the Canadian and U.S. armies apply to fighting vehicles and equipment serving in arid climates.
CP 7022 wears the grey, red and black colour pattern of modern Canadian and American warships.
CP 7023 wears a two-tone gray paint scheme designed after the livery applied to Canadian and American fighter jets.
CP 6644 wears the camouflage colours applied to Royal Canadian Air Force "Spitfire" fighter planes flown at the Allied invasion of Normandy, France, on June 6, 1944.
Four of the five locomotives bear a Canadian flag on one side and American on the other. CP operates in both countries and employs veterans of both countries' military services.
