The WMR ordered No.17 from the
Baldwin Locomotive Works. It entered service on 10 June 1902 and was at the time the most powerful locomotive to operate in the country. No.17 was the only
2-8-2 "
Mikado" to run in New Zealand. At the time of its arrival, it was the largest engine in the country. It was a
Vauclain compound, and its trailing truck bore similarities to the
Q class, the world's first
4-6-2 "Pacific" type then under construction by Baldwin for NZR. The Baldwin Locomotive Works had taken the design of the locomotive almost directly from the original Mikado, that they built for the
Nippon Railway of Japan in 1897. No. 17 was the Japanese engine fitted with a
Q class boiler. It was then only the third Mikado to be built in the world. The locomotive was designed to haul trains on the WMR's
steep main line between
Wellington and
Paekākāriki, and it proved capable of hauling a 280-ton freight train up the
steep grades. This line became the southern portion of the
North Island Main Trunk Railway when acquired by NZR in 1908. 2-8-2 No. 17 with the first Mikado class built for the
Nippon Railway in 1897. == Withdrawal ==
