― 満鉄の産業輸送を支えた 1-C-1（2-6-2）機 ―
南満州鉄道（満鉄）のプレニ型蒸気機関車は、1-C-1（2-6-2）軸配置を持つ中型タンク機関車で、主に工場・製鉄所・鉱山などの産業輸送で活躍しました。形式名の「プレニ」は、アメリカ式軸配置呼称で 1-C-1 を示す**「プレーリー（Prairie）」の“プレ”と、同系列の2番目の形式を表す“ニ”**を組み合わせたものです。
この形式は1930年代に日本車輛製造株式会社などで製造され、旧満州国の各地で資材輸送・構内入換・作業員輸送など、多用途に使用されました。特に重工業の中心地であった鞍山昭和製鋼所では、日々の操業を支える重要な役割を担いました。
プレニ型は、
– 小回りの利く軸配置
– 産業用に適した中出力
– 整備性の高い構造
といった特徴から、長期間にわたり現地で使用され、満鉄の産業インフラを支えた存在として知られています。

― A 1-C-1 (2-6-2) Locomotive that Supported Industrial Transport on the South Manchuria Railway ―
The PL2-class steam locomotive of the South Manchuria Railway (Mantetsu) was a medium-sized tank locomotive with a 1-C-1 (2-6-2) wheel arrangement. It played an important role in industrial transport, serving factories, steelworks, and mining sites across the region.
The class name “PL2” combines “PL,” derived from the American wheel arrangement term “Prairie” for 1-C-1, with “2,” indicating the second type in this series.
Built in the 1930s by manufacturers such as Nippon Sharyo, these locomotives were used throughout Manchukuo for a wide range of duties, including material transport, yard switching, and worker conveyance. At the Anshan Showa Steel Works—one of the major centers of heavy industry—they were indispensable to daily operations.
The PL2-class became known as a reliable industrial locomotive thanks to features such as:
– A wheel arrangement well-suited to tight-radius curves
– Moderate power output ideal for industrial service
– A simple, easy-to-maintain mechanical design
These characteristics allowed the PL2-class to remain in service for many years, supporting the industrial infrastructure of the South Manchuria Railway.
