Earlier this month I travelled up to Hamilton while a family
member was in Waikato Hospital. While this is a railway and industrial history
blog, I want to acknowledge the surgeons, doctors, nurses, assistants, and all
the staff at Waikato Hospital. They were absolutely fantastic, and we felt so
much better knowing our family member was in the best possible hands. After a
few days post-surgery, we knew the worst was behind us and that recovery was
well underway.
We had chosen a hotel close to the hospital to make
travelling back and forth as easy as possible. In between hospital visits, I
tried to get down to Frankton Junction whenever I could, to experience one of
New Zealand’s railway hot spots firsthand. It just so happened that the hotel
was only a five minute drive away.
Frankton, located near downtown Hamilton, is the junction
between the electrified North Island Main Trunk and the East Coast Main
Trunk.

Main Trunk enters from the lower centre of the image, curving to the left
before heading northwest towards Te Rapa. The East Coast Main Trunk approaches
from the upper right, sweeping around before joining the NIMT.
Hamilton forms one corner of the famed KiwiRail 'golden
triangle' between Auckland, Hamilton, and Tauranga. This route is the
busiest freight corridor in New Zealand, connecting the Port of Tauranga with
Auckland. The Waikato is also a significant producer of freight, with major
Fonterra sites and inland port facilities across the region.
Alongside the steady procession of freights and local
shunting movements on the NIMT and ECMT, Hamilton is also served by the Te
Huia Auckland–Hamilton commuter service and the Northern
Explorer, the long-distance passenger train between Auckland and
Wellington. Unfortunately, these passenger services and some freight services
were not operating at the time due to a shutdown of the Auckland rail network
for major works over the holiday period.
Some freight services between Tauranga and Auckland instead
terminated at a temporary container terminal at Frankton, where containers were
transferred to road transport for road bridging between Hamilton and Auckland.
A shunting locomotive is taken south on the morning train and used to work the multiple sidings in and around the factory, being far better suited to this task than the DL class. The shunting loco then returns to Te Rapa on the afternoon working.
DL's 9636 and 9469 head onto the ECMT with a light engine move to the inland port at Ruakura.12/01/2026.The Ruakura Inland Port is a relatively new facility, opening in August 2023 to serve importers and exporters across the Waikato. It is a joint venture between Tainui Group Holdings and the Port of Tauranga, and represents another growing source of traffic for KiwiRail.
After grabbing another fast-food dinner, I returned to Frankton Junction in the twilight and was rewarded with another eastbound ECMT freight, this time led by DL 9319.
In recent years though, the EFs have enjoyed a revival, with a much-needed overhaul and upgrade programme returning several units to service. While they no longer dominate the NIMT like they once did, they continue to play a valuable role in hauling freight across the central North Island.
While the locomotives look good in the new blue KiwiRail livery, I still think they looked better in the original “fruit salad” scheme of orange-red, yellow, and grey, complete with the large white numbers along their sides.
My timing couldn’t have been better. Just as I reached the middle of the bridge , the Te Awamutu shunt appeared around the curve, easing its way toward the yard at Te Rapa.
Rather than continuing through to Te Rapa, the train came to a stop. After about ten minutes, a low-speed light appeared on the signals and the DL carefully worked its train through the junction and into the sidings serving the temporary container terminal at Frankton.
One thing that quickly became apparent to may as I stood on the platforms was that, with the exception of the DCs and EFs, the vast majority of trains I saw were hauled by the DL class. As someone living in the South Island, these locomotives are still something of a novelty for me, and I was more than happy to watch them pass by. Saying that, I can easily see how it might begin to feel a little repetitive over time.
We are very lucky in the south, where we're witnessing the final years of the DX and DFT diesels in New Zealand service but it won' be long before we're in the same situation with most trains hauled by the new DM class.
If you find yourself in or around Hamilton with an hour or two to spare, I would highly recommend a visit to Frankton Junction, an absolute mecca for New Zealand railfans.
And that's about it.
