Greg,
New Zealand had a number of locomotive first in the design of steam loco's, the Mountain wheel arrangement being one of those, with the 1908 X-class Compounds
"X" class (compound) steam locomotive 445, 4-8-2 type., between 1910 and 1949
Reference Number: APG-0368-1/2-G
"X" 445 steam locomotive (compound), type 4-8-2 (maker's no 100/09), built by NZR Addington. Photograph taken by Albert Percy Godber between 1913 and 1949.
the original J class 4-8-2's were based on the NYNH&H I-5 and N&W J depending on who's writing the facts, you could compare them via google images. My Uncle flew Kittyhawks before converting to Corsairs in the Soloman Is during the big Pacific war.
I did post this awhile back, without the diesels, [

Kevin,
the NZGR was still building new J
A alongside imported Diesels, a year after the introduction of the US built D
A G-12's, it was the performance of those that killed the modern Steamer here, they were just too good. The reason for the longevity in the South Island was due performance on high speed Passenger services over the Diesel and steam heating prior to the building of the self-contained Steamheat Vans.
