Nickel Silver Plated Brass Insulated Wheelsets
These wheels follow NMRA RP-25 Standards.
One wheel is insulated from the all-metal axle.
The entire wheelset is non-magnetic.
The axle length is approximately 1.006" (+- .004").

28" wheels are used on modern Tri-Level Autoracks, and some older intermodal cars - check your prototype.
33" wheels are used on 70 ton capacity cars (CAPY approximately 150,000 LBS).
36" wheels are used on 100 ton capacity cars (CAPY approximately 200,000 LBS).
38" wheels are used on 150 ton capacity cars, primarily the center connection trucks on modern intermodal cars with 36" wheels at the coupler ends.

The CAPY information is typically printed on model freight cars and can be used as a guide. Some cars have the wheel size printed on the sides or ends of the car in the data. If you are ever unsure of which size to use, you can simply replace the wheels currently on the car with the same size.

Wheel diameter can be measured with a caliper:
28" wheels measure (28/87.1=.321") in HO scale.
33" wheels measure (33/87.1=.378") in HO scale.
36" wheels measure (36/87.1=.413") in HO scale.
38" wheels measure (38/87.1=.436") in HO scale.
(87.1 = HO scale to prototype ratio. HO scale is 87.1 times smaller than the prototype).
