Starting with the Dash-9 (introduced late 1993), many GE six-axle locomotives have used a truck dubbed "Roller Blade" style by railfans. (This is the NON-radial truck used on C44-9, ES44DC, and some but not all AC44 and ES44AC: for primary suspension each journal is flanked by a pair of prominent springs in a "Napoleon Hat" bracket.) I vaguely recall reading, when it was new, that the design was partly due to Krupp, the German manufacturer which has at times been a GE partner in the export locomotive market.
I just noticed a drawing "Jane's World Railways" 28th edition (1986-1987), page 121, of a double cab locomotive with an FDL-12 engine: caption doesn't identify the exact locomotive portrayed, but of the units with photos in the same article (a one-and-ahalf page Krupp entry in the "Manufacturers: locomotive and rolling stock" section of the book) it most resembles a UM22C for Botswana Railways: a 96 tonne (ca. 212,000 lb) unit built for 3'6" gauge.
The truck LOOKS very similar to the "Roller Blades" design: similar spring arrangement (and, like the "Roller Blades" truck, with all three traction motors on the same side of their axles).
