Working with sound isolation for the Navy the noise-vibration-can be lessened by of of two (or both) methods: isolation or increase mass to change the vibration (Noise)wavelengths. Get the weight up, or as already suggested more practically, smoother trucks and or sound isolating foam inside. I personally like to play train Sound dvds to ‘set the mood’! W. Smith

Know that trick. Probably will do it on the coal gondolas. Nonetheless many thanks for the reminder.
For more "ordinary" trucks the list goes on:
- finding new .88 wheel sets
- grinding away the brake shoes
- making the bolsters accept Kadee brake pads (if possible at all! Some side frames are clipped to the bolster, or screwed on horizontally.)
Before I would even think about doing this to maybe 50 brass cars with at least 30 different (model manufacturer) trucks I purchase new ones which need NO work and I am happy ;-)

But unfortunately these truck springs of course were real springs making for that inaccurate "too light" look.
You can do the Richard Hendrickson trick, just glue a little square of styrene behind the springs. Then you can't see through them, and they look greatly better. This would only be a choice if the trucks are actually the right ones for the car.
