Locomotives

A number of different locomotives will take you on your KiwiRail journey. The type of locomotive will depend on a number of factors, including the size of the train and locomotive availability.  The Northern Explorer occasionally makes use of the EF locomotives on the electrified section of the North Island Main Trunk line between Hamilton and Palmerston North.
