Really? I always thought it was caused by stack fires due to poor internal planning. This problem is more common with GE roadswitchers, mainly the U-boat series and some AC4400CW's (unsure about AC6000CW's). Usually the hood section would need repainting which means one end could be a different shade than the other. Some Class-1 railroads repaint the entire locomotive which is costly ($5000 per loco?).
Of course, it is interesting to see.
That make sense. Thank you for the explanation.

The fuel in these lines is under 50-80 lbs of pressure. A leak in any of these lines sprays fuel up and around the hot exhaust manifold and ignites. They look pretty bad coming into the shop but we just replace the damaged parts and get them back out on the road without repainting them. If you see an EMD locomotive with the paint burned off ike that, Its usually caused by an oil fire or a bad exhaust leak since most of the fuel lines are inside the engine and any leaking fuel is just drains into the crankcase. This will dilute the oil but oil sampling and analysis will pick it up.

If that photo has been a UP engine I would have suggested flamers from this forum;)
