Re: Brass freight car noise - NOT TRUCKS
I might (half seriously) suggest obtaining a set of noise cancelling headphones. You could then take the guts of said headphones and install them within the offending boxcar. I believe that they are

Re: Brass freight car noise - NOT TRUCKS
The problem is that a brass car, especially a box car is, in the reality of physics, an empty metal 'can' on wheels.
As such it audibly magnifies any drumming disturbances pick up when rolling along,

Re: Brass freight car noise - NOT TRUCKS
Hi James,
Try one of the thin Kadee fiber washers between the truck and the freight car bolster to deaden the noise.

As might a stick of styrene carefully wedged between the sides, perhaps glued in place. CAREFULLY as you don’t want to inadvertently deform the car sides by pushing them outward so make the stick

Re: Help with B&O M-59 Ladder Size Approximation
Bruce,
I concur with the others, 18" wide by 18" vertical spacing. YMMW model works has this combination of rung width and ladder rung vertical spacing.

Re: Brass freight car noise
Indeed. The hollow brass body is acting as a sounding board, amplifying the vibrations caused by the wheels on the rails, the same as the hollow body of a stringed instrument amplifies the vibrations

Re: Brass freight car noise - NOT TRUCKS
You could try Dynamat. They use it in cars under the carpet to keep out road noise. You can get a small sheet for around $30. That would be enough to do a fleet of brass cars.

Bruce I would agree, 18”. I believe that was a standard ladder width. The car number could be used to find the car in an ORER listing or full photo of a car from the same series, that could off more

Foam rubber, or artificial foam as is more likely, might quiet such a car. However, both materials deteriorate with age and become flakey, making a potential mess. White styrofoam blocks

Re: Help with B&O M-59 Ladder Size Approximation
if you know the wheel spacing of the
truck, take the photo tona copy.shop
that has a scaleable copy machine and
increase or decrease the size until you
get the right size, you'll also need a
scale

You might try, for a boxcar, packing it with foam rubber. If you are really desperate, fill the car with non expanding spray foam. Given the sloppiness of using spray foam, I would do it on a painted

Will someone please address the question? Yes, I have replaced the trucks, as stated in the original question. I want to quiet down the tin sound of brass cars. Any suggestions on making them quiet?

Re: Brass freight car noise
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
