Continuing the theme of export deltics... I thought since the Union Pacific was always one for trying slightly different ideas (3 cylindered steam locos, something virtually unheard of in the US), the use of articulated locos, their flirtation with gas turbines (including one coal burning one), then the deltic would have appealed to them. Also, I'm sure the fact that DP1 was at the time the most powerful singe unit diesel loco in the world at the time would have appealed greatly to UP who have always been keen to have the biggest, the best and most powerful!
Who here wouldn't want to see and hear one of these slogging it out, climbing Sherman Hill at the head of a long freight train?
As ever, credit goes to 2509-Silverlink for the original image of DP1.
