Product Information:
HO Scale 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 1.006" (+- .004")
Wheel diameter can be measured with a caliper:
33" wheels measure (33/87.1=.378") in HO scale.
33" wheels are used on 50 & 70 ton capacity cars (CAPY approximately 150,000 LBS or less).
Cabooses can use either 33" or 36" wheels depending on the prototype.
(87.1 = HO scale to prototype ratio. HO scale is 87.1 times smaller than the prototype).
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.
Wheelset finish has been improved to have a dull blackened appearance to be more realistic without the immediate need for weathering. It also provides a nice base starting point for weathering if desired.
