I believe the material of the actual wheelsets will have a bearing on noise as well. Those with plated/polished nickle-silver wheels (like Kato and Atlas) will have less or at least different noise from those with steel/sintered iron wheels (Athearn, early Proto 2000).
Replacing steel wheels with n/s ones from JayBee or NWSL has improved the sound of many of my older Athearn diesels, which otherwise had a quiet drive line.
