We call it Bo-Bo-Bo, and it was designed that way for the sharp curves. From what i have heard/read , these are a smooth riding loco, and I've never seem one jumping around on the corners, nor have i heard any screeching on sharp curves.
I am in Palmerston north at the moment , the southern (and main) depot for the elcetrics. There are 4 parked up outside, 2 look as though they have been parked for awhile, 2 look like recent additions to the pile. One is in the latest Kiwirail livery. Whilst there ,, a long container train came in hauled by 2 of the new DL locos. But it could have come form one of the 2 diesel branches that come into Palmy from the North.

The only train trips I regret are the ones I didn't take.
