Who makes Alco RSD-1 in HO scale?

No-one makes one in plastic, if that's what you're after. I seem to recall a brass model from way back, although I'm not 100% certain about that.

Assuming you want the hood version and not the ARR cab unit, you could kitbash one from an RS-1, a NSWGR 40 class cab, and some three-axle trucks with new frames.

You could try matching an Atlas RS-1 shell with their RS-4/5 frame and trucks. Then it would be a simple matter of tapering the cab a little where it meets the cruved roof section.

The trucks would be all wrong. http://en.wikipedia.org/wiki/Image:RSD-1.jpg You''d have to cobble up new truck side frames and it appears the axle spacing is closer the the RSC-2 than to the RSD-4/5.

Thanks guys!

I didn't realize most of those engines ended up in Soviet Union, I thought some were used here hence I thought someone made a model. 

 I thought someone did too! A RSC-2 could work if you toy with the shell.

I know it wouldn't be exact, but I was thinking "close enough" would better than doing without.

Giving the feel of the locomotive without going to extremes.
