Union Pacific 6936 is an EMD DDA40X locomotive owned by Union Pacific Railroad (UP). It is the sole example of the "Centennial" type that is still in operation, and thus is the largest operating diesel-electric locomotive in the world. It is occasionally used on both excursion trains and in revenue freight service.
At one point UP 6936 struck a vehicle at a grade crossing and suffered some damage to its front end. After the damage was repaired, a winged UP shield was painted on the front.[citation needed] It was also repainted in the current Lightning Bolt paint scheme and had a rooftop air conditioning unit installed.[citation needed]
