Greenberg says it's AC w/reverse. You should be able to tell just by looking at it from the bottom.

Right no reverse but that is an AC motor,
That is a series wound universal motor, as are almost all of our postwar and prewar trains. It has no reverse unit, so it will only run in one direction, but will run on AC or DC.

It should only fit one way. If you force it in backwards, the fiber side plates will break.
So... don't force it. 
You can run it on a track, see which way it goes, and mark it with a Sharpie.

just an fyi if you did just pick this up for the motor alone. the GE switcher body looks to be in good shape and while this is by no means a rare piece, keep in mind that there are many more good motors than nice shells out there, so someone would likely be interested in it.
also, if there are more cars like the 4-wh SFRD boxcar, 4-wheel plastic collectors are very fussy about having four intact truck sideframes; a value that drops drastically with even the smallest chip out of these rather fragile pieces.
good luck with your project.

Looking at the brush side picture, the side to the right with the rectangular tab should be the front. The tab is where a reverse unit and smoker would mount, if it had one, and Marx always had them towards the front.

Two of the Marx drives could not be used because the drive gear is part of the flanged wheel. The gear is even with the outer diameter of the flange and bounces through switches and activation tracks.
Just so you know that yellow painted decoration on that piece is somewhat rare and sought after. The usual decoration was gold and it didn't wear well in handling and is almost non existent on most examples.

Oh' OK. I guess I missed that part. In any case these are neat little engines and are one of my faves.
