CN 3300 is the first one out of the Fort Worth plant in new paint and with a new cab. I haven’t seen anything official yet, but I think it’s a pretty safe bet that this is a DC-to-AC rebuild from one of the CN Dash-9s that had been seen at this plant in recent months.
Well, perhaps - just perhaps - when you are “sweating the assets” with single locomotives pulling huge land barges like 1920s 2-10-2s on drag freights, the ability to lug at very low speed for a very long time without damaging the traction motors is probably very valuable.
