This started as a doodle in math class, which eventually got out of hand... The basic design is that of the RSD-35E, or DL535E, slightly modifed. I named it the CX-620 to propose a series of export locos based on the Century design. In reality, the RSD-35E does look like a narrow gauge Century.
Also just to note, the truck design is the best that I could recreate the B-L-H trimount design...
