I don't have any calipers handy and was wondering what axle length wheelsets would go with the Athearn N railroad cars. 



Thanks for your support.

most repalcement wheels (FVM, Intermountain) have the same axle length sinc ethey represent a prototype that the same length.  The wheels come in different diameters now with different diameter axles, which is really what you need to be concerned with.  As i recall, both FVM and IM labale some of their wheels for specific manufacturers.

The same size used on MT trucks .540

Athearn have changed their axle length size some time ago.  Originally their axle length was the same as Atlas  (.553),  then they changed to .540.  It is not easy to detect because the trucks look the same as the Atlas trucks, but have shorter axles.
Now that they use McHenry couplers it is no longer a problem.
