The door apparatus on the M8 is made by Vapor (same in the M7) and so will be on the M9. Has nothing to do with the car manufacturers, just newer versions of the same door system. Design really hasn't changed much, what you're hearing is the door motor as it spins,

Okay, so both Kawasaki and Bombardier buy from the same supplier. You're saying the technology has improved over the years then? But why were the doors on the M-1/M-3's so quiet in 1969/1985?

Different mechanism altogether. The M1/M3 have doors mounted on simple roller bearing tracks, and side mounted operators that open and close the doors through an over-center lock type linkage

The M7 has an overhead mounted jackscrew with fine threads which spin at a high speed, hence the three stooges sound when they open and close.

The C3 has a similar setup, only the jackscrew thread is much broader.

I believe the M9 will have door systems made by Fuji

Thanks! Let's hope Fuji knows how to build a quiet door system.

with the buy american concept, most components are US made including air conditioners, door operators, toilet systems brake components, etc etc.
If Conductors are in charge, why are they promoted to be Engineer???

Doors are without a doubt Fuji. There is no buy america component on the M9, they're not federally funded. The M9A will be federally funded and a separate procurement with a buy america component

BuddR32, I assume the M9A is for Metro-North? Why would theirs be Federally funded but not LIRR's M9's?

Nope, M9 and M9A will both run on both railroads, the distinction this time around is the funding source.

Well whover builds the friggin' door mechanisms, they'd better be quieter than on the M-7's 'cause those noisy doors are a disgrace to modern industry. :( And the M-8's have already proven that the industry can do better.
