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.
