Hi there! This question has been in my head for quite awhile now: What was done to the F40 Rebuilds when they were rebuilt between 2000-2004? Any answers are very much appreciated!

Was the new engine room door added between the prime mover and the main generator/turbocharger, or is it the one between the air compressor & HEP generator?

The difference there were between, the 1025 and 1050 series units I think have been standardized, since M-K (now MPI) rebuilt them all, so the specs probably match their latest model at the time, the F40PH-3C. They retained their control stands, though, I was worried they would end up with desktops like the Coaster, ACE and Caltrain units. Real F40s have a control stand!MK did make a few minor modifications to the control stand before they started making major changes. I have to agree that real F40s have the control stands! The turbocharger is definitely different from the screamers(obviously since the turbocharger is one of the LOUDEST components), though I don't look at the ones in the MK units too often.
I also wonder if the turbocharger or exhaust system may have been redesigned, there is a much lower bass exhaust note with these engines than anything else in the fleet, and it didn't seem like that before! If you are in a K-car behind a rebuild coming into say Back Bay or Porter Square the vibrations will rattle the car like it's coming apart!
