New Zealand Railways (Kiwi Rail) delivers 16 new DL class locomotives to Te Rapa;

Kiwi Rail delivers 16 DL locomotives

IF all locomotives were working (which they weren't), the total amount of available power would have been 57,600hp. Note the following stats;

Again, IF all locomotives were working (which they weren't), the total amount of available power would have been 120,400hp. Note the following stats;
