It is only after the fifth notch that the turbo pressure builds up. This smoke seems to be a result of notching up very rapidly to the fifth notch. The smoke gets cut off as the governor cuts in. The WDM2 in the good old days had a more relaxed setting of the governor. Now a days the governors seem to be very sensitively set ( fuel economy) and cut in to prevent excess fuel consumption.

In case of Alco's the reason for smoke is turbo lag.
When loco is notched up, the turbo takes some time to gain RPM and till then the loco smokes.

I admire Ashwin's drive and tenacity to reach difficult spots - including under various railway bridges. Amazing work - that is usually done by Ashwin all alone.

Hey Mr. Boatman, your snaps are getting better by the day...keep them coming. Super Stuff, very very refreshing indeed. The best part is that off late Ashwin has been providing us with quite a few captures from a boat or river bed, but still manages to garner praise. Keep it up man!!!
