quote:Interesting info. Is this a Lionel "Atomic" motor, and was it used only in the early turbine and Berkshire locos?
While it carried a different part number, the 2332 GG-1 used almost the same motor, including the loose ball bearings. I think the brushplate carries the "Atomic" marking.
Here is the page on the 2332 GG1 motor. It includes a description of how it differs from the 671 (also used on 726) motor.
