No doubt about it that it’s an exhilarating picture. It’s a remarkable picture indeed. Excellent shot. I just wanted to know the cause of the smoke.

Zubin - it's simply an ALCo! They're known the World over for their responsiveness to the driver's command, which means if the LP asks for a rapid increase in lots of notches the loco replies by dumping an excessive quantity of fuel into the cylinders - not economic but dutiful and spectacular! Just about any ALCo taken from relatively low to high notches will smoke heavily, although later MLW and Bambardier examples do rev and load in a more controlled manner (less responsively) and consequently don't smoke anywhere near as much. Of course the possible causes you mentioned and the condition of the injectors, fuel pumps (and, significantly, their settings), turbo, load control system etc will make a difference, it's probably the setting of the maximum fuel stop that determines a true heavy smoker.
Regards, Dan.

Thank you Dan for your most logical and relevant explanation . In the good old days all WDM2 used to smoke a lot. Now it seems that changes have been made to the governor and even if the LP notches up like crazy the governor cuts out the sudden spurt in oil injection. In this particular oil burner that we see in the picture the governor for some reason has not cut out the sudden spurt in oil injection. Or it could be any of the reasons that have already been mentioned.
Regards.
Zubin.

Great capture. I think the smoke must have entered in your mouth too.

Wow! This is the smokiest ALCO picture I have seen so far.

So than what is it ? A leaking turbo oil seal ? Jammed / stuck up injectors ? Or the retard timing ?
