Translation guide
A railway with a track gauge narrower than the standard 1,435 mm. In Japan, this typically refers to the common 1,067 mm gauge, but can also refer to other narrow gauges like 762 mm for special lines.
The learner wants to refer to a railway that uses a narrower gauge than standard, in a general or descriptive sense.
The standard technical term. '狭軌' means 'narrow gauge' and '鉄道' means 'railway'. Suitable for formal or written contexts.

Loanword from English 'narrow gauge'. Commonly used in railway enthusiast circles and some signage.

Once, a light railway connected the village and the town.
The learner wants to talk about the typical narrow-gauge lines in Japan (JR, private railways) without necessarily using the technical term.
In everyday conversation, Japanese people rarely specify the gauge. Simply saying '電車' (train) or the line name (e.g., '山手線') is sufficient. Adding '狭軌' can sound overly technical.
日本の鉄道の多くは狭軌です。
Most railways in Japan are narrow-gauge.
Refers to conventional lines (as opposed to Shinkansen). Most conventional lines in Japan are 1,067 mm gauge, so this term often implies narrow gauge by context.
在来線は狭軌ですが、新幹線は標準軌です。
Conventional lines are narrow-gauge, but the Shinkansen is standard gauge.
The learner is discussing miniature, industrial, or forest railways with a gauge narrower than 1,067 mm.
Technical term for railways with a gauge of 762 mm or less, often used in legal or engineering contexts.
この森林鉄道は特殊狭軌鉄道に分類されます。

Often used alone to refer to very narrow-gauge lines, especially in tourist contexts (e.g., 'ナローゲージのトロッコ列車').

I rode a small narrow-gauge train.
When specifying the gauge, use millimeters with 'ミリ' or 'mm'. Example: '1067ミリゲージ' (1,067 mm gauge). The term '狭軌' alone is usually understood as 1,067 mm in a Japanese context.
Saying '狭いゲージの鉄道' is unnatural. Stick to the terms above or simply describe the train/line without mentioning gauge unless necessary.
