CP SD40-2 #5755

    I found this photo of CP #5755 on LocoPhotos recently. I wonder why CP would change the air filter system on this unit. I could have sworn reading somewhere that the reason for the inertial air filter design was to isolate the filtered air for combustion and what not from the hot oily air of the engine compartment. This seems more like the older setup used on first generation diesels. Maybe some diesel expert out there can explain this?

  Thanks for the Fix! I must have been running low on coffee!

  The inertial air filter equipment still appears to be there.  The 'new' intake filter is different.  The carbody filters further back have nothing to do with the intake air.  The air is sucked in to the unit just behind the cab.  It is 'processed' and clean air is used by the turbocharger.  Excess air 'floods'  the engine compartment and provides a 'positive' air pressure.  Air is 'exiting' the carbody through those small filters, leaks in the doors, and cooling fans.  Positive air pressure was incorporated in the GE U25B and EMD followed with the GP30 model.
