ResumoTwenty-two, 3 M W freight locomotives are being supplied to New Zealand Railways Corporation as part of the 25 kV electrification project of the North Island Main Trunk route. The mountainous terrain of this route favours a Bo-Bo-Bo configuration with its good curving performance. Separately excited d.c. traction motors fed from microprocessor-controlled thyristor bridges enable 1000 tonne trains to be started on a I in 50 gradient. The provision of a regenerative brake offers significant energy cost savings.
