Hmm American locomotives with American looking freight cars. Would like to see a retired one of these get shipped to a shortline/museum in the US.

Forgive me if this is thread is too old to dig up.
All of the units pictured should be narrow gauge. From what I've read elsewhere, the reason for the BB-BB configuration is because the narrow gauge traction motors in a C-C setup cannot fully utilize the full horsepower of the unit. Basically, if you just narrowed the gauge of the original trucks with narrow gauge axles and traction motors, the units would have to be de-rated in order to not burn themselves up. The extra two traction motors better balance the horsepower across all motors. I forget where I read this or I would have included the source. It is likely that dispersing the load across two more axles is a contributing factor as well. Either way, these are pretty wild modifications! Tyler
