Very nice gathering with some excellent models. A question about the 4-6-2 Pacific though, this is not an existing prototype, but has such a type ever been considered by NZR?
Yes, general arrangement plans were prepared for both enlarged 4-6-2 and 4-8-2 designs, a further development of the K / Ka / Kb types, the 4-8-2 to have 6-wheel tender bogies. A Christchurch model engineer made a 5inch gauge version of the 4-6-2 version many years ago, referred to as a "Super Q".
You can see an outline drawing of the "Super Q" as it was known on the back page of "Steel Roads of New Zealand" edited by the late Gordon Troup. The "Super X" the 4-8-2 also shows up there. Very exciting to see a working model.
@@anoldguydoesmaths7082 I now naturally had to find a purchase tis book, it was missing from my library of NZR books. A couple on sale in the UK but found one in Finland as well, no delay by customs and import fees as Finland also is part of the EU. Post rates from NZ or US to the Netherlands have become too expensive, I pay more on postage alone than I paid for the book plus postage from Finland.
Most diesel powered ones are either petrol lawn mower engines or a lot of the time electric and to expand on that and answer the electric one it's usually little electric dc motors which are then chain driven to the axles
As I can make out from the video one of the diesels, the DH 2018, is powered by a real engine, like a 1 cylinder Honda or Briggs & Stratton equipment motor. The other diesel and electric models all run off batteries, most often 12 or 24V car or truck batteries, and then using windshield wiper motors or motors from wheelchairs and mobility scooters, these all can be sourced used at a fair price. The large diesel DFT 7361 has digital sound on board using a sound chip from OO/Ho scale but connected to a car amplifier and speakers for the beefy sound. I'm not sure how they hooked up the chip to the speed controller of the loco but there are surely commercial solutions to do this.
As I watched this I was immediately taken back to my childhood in the far north Kaitaia in the 60s.My dad had a similar car. I remember leaving our grandmothers to return home we had to climb a small hill which the car would often require a 2nd run to get over the hill. Good memories. I look around at all these modern cars that look the same. I miss the 60s and 70s.
I have always liked the BTC. I don’t mean this in a derogatory way in the slightest, but none of their locos look like polished show ponies. Everything looks just like it would have in service many years ago, especially the Cb. She looks great.
I love these old cars but 60 mph in one like this is pretty uncomfortable for me. I have a couple 1938 Mopars. In my Plymouth with 4.11 rear end, 45 is very solid and stable. 50 gets a little buzzy. At 55 mph the feels pretty strung out. My ‘38 Chrysler 3.90 rear end with OD, 60 mph is easy. 70 is fine, power wise. But handling, braking and lack of any safety features keeps me back down in the 50-55 mph comfort range.
Not that much. The Ja's mainly had small improvements over the J's like ball bearings in the axles and driving rods and larger firebox area. As well as Ja class being built in NZ where J class was built in the UK
