This GE doesn't seem to be heavy enough for the BB set of trucks. Just curious on the weight of the loco, Guilherme.

They have BB trucks because they are narrow gauge and need to spread the axle load. They look odd running on narrow gauge rails
|
The GE BB40-9WM axle-load is about 22tons. They have 176 meter tons of total weight.
|
My friend, this locomotive weighs 160 tons...
|
They've met some changes which increased the weight, as the new bigger tank.

@Nigel, it's not the axle load (I doubt it's an issue on Brazil's heavy-haul railways) but the electrical load that's the limiting factor. The narrow-gauge traction motors are smaller and would be unable to take full advantage of the locomotive's power output with three-axle tucks.
