I was railfanning at the Union Pacific railyard just outside of Milwaukee and I saw this switcher type locomotive. After doing a little research, i guess it is a RP20BD and it was built in 2007. It is not in the era that I model, but I really like the look of this loco and am wondering if anyone knows if these have ever been manufactured in N scale...
If not, has anyone out there ever kitbashed or scratch built one? I would love to know how and see some pictures. Any infoormation about this engine would be greatly appreciated. I look forward to hearing what the forum community has to say. Thanks! Cheers!

Generally called a "genset" loco. Do some searching around, you'll find more about in Wiki, and rrpicturearchives.com, and what the loco was originally built as, and for which road.
A lot of gensets were rebuilds from other locos.
Apparently the Y before the number, and after the UP means it's a yard switcher.
I'm not sure if any one offers these in N scale. I never thought of gensets interesting enough to attempt to build one.

This locomotive switcher is not being manufactured in N Scale. I have seen it being made in HO.
Although it's also out of my era too. I like the shape of the Genset.

I seen that Shapeway model during my search Bear. It looks good.
Now one will need to find out the length and truck spacing, to see what power train and frame would work. The trucks look like the Blomberg trucks found on the GP locos.

They tell you an Atlas B23-7 with Blomberg trucks in the description. The supplier they list is the guy who is selling the Shapeways product. The links to his website don't work. There is an alternative website and some of those don't work.
That's sets off the red flags for me.

I just checked out Bear's Shapeway link, and it worked OK for me. The guy has some nice stuff.
Using the B23-7 makes sense, as that is what the prototypes used, a lot of GE B locos for the rebuild.
Looking at the picture the OP posted, it looks from the GE FB2 trucks that this loco was maufactured off the frame of some older GE, a B23-7 makes sense. Hense I would think the frame of one of those would be a good starting point for a kitbash.
In HO, Atlas did a model of one of the Gensets made by NRE (of which the OPs picture is not) but thats the only production Genset I know of, so I guess it's down to kitbashing, especially in N scale.
Good Luck!
EDIT* Just took a look at Bear's link and I would like to note that that is a Natonal Rail Equipment (NRE) Genset. The OPs photo is a different manufacturer (I will arbitrarily say Motive Power Industries). The main difference is the nose and front window design.

The Y is part of the reporting mark. Its reporting marks are UPY instead of UP. UP has used this reporting mark for some yard power since their fleet is quite large.
