The scale is N.

Which scale are you referring to?

In HO scale, Atlas has never offered an SD40, and they have not offered a locomotive with a chassis that would fit an SD40. They closest are the SD24 and SD35, both much shorter than a SD40.

I don't know about other scales.

Hell all,

I was wondering if Kato and Atlas SD40 shells are compatible? I have a chance to purchase a Kato SD40 Burlington shell, but want to put it on ATLAS loco that I already have DCC installed on.

Is it that simple, meaning just to pull one off and replace it with the other?

Thanks for your help.
