I'll start with my top 3:
1. EMD SD80MAC
Unfortunately word has it all of them have been scrapped, but they are and always will be #1, simply because of two things, the design and prime mover.
The 80's were sortof designed like the Boeing 777 with one word in mind, simple. Not many sharp edges, no fancy, futuristic cabs, just a simple design, but waaaaay longer, and a pretty cool looking tail end though.
My second favorite part is the prime mover, if I wasn't a railfan, was told an SD80 had 5,000 horsepower and shown a picture, I wouldn't believe it. However, hearing them in person makes you think otherwise. Correct me if I'm wrong, But I think the SD80MAC was the only locomotive that was successful with 5,000 or more horsepower (when I mean successful, I mean not blowing crankshafts into smithereens or stuff like that

2. GE P40DC/P42DC
These are (in my opinion) the best looking passenger engines ever made, they are very sharp looking, they sound INCREDIBLE when running in HEP mode and have worn and created some pretty badass liveries.
They have become the stereotypical locomotive for Amtrak trains and it'll be sad when the last P42 is retired from the Amtrak roster. However other railroads have taken some and have plans to use them for awhile, such as CTRail.
3. EMD/MPI SD40-3 (Sorry AARR
![Laughing :lol:](http://www.railroadfan.com/phpbb/images/smilies/icon_lol.gif)
I like this engine, unlike the SD80's where I like a clean design. I like these, CSX took a...I'm going to get a lot of crap for this...boring looking engine (SD40-2) and made it look like the entire locomotive model type was designed in the 2010's. It's just such a sharp looking engine, and word has it CSX may be *possibly* starting the program again.
I also like the way their ditchlights flash and the micro-precision K5LA's they've got, Don't know why

I'd love to hear what everyone else's are.
