British industrial narrow gauge railways

British industrial narrow-gauge railways are narrow-gauge railways in the United Kingdom and the Isle of Man that were primarily built to serve one or more industries. Some offered passenger services for employees or workmen, but they did not run public passenger trains. They are categorized by the primary industry they served.

Power stations were some of the last regular users of industrial steam locomotives in the United Kingdom, although most of these were standard gauge. However, several power generation facilities used narrow-gauge railways.

Many construction contractors maintained depots that included narrow-gauge equipment in store and under repair. While some of these were temporary locations and often unrecorded, others were long term yards with extensive stock and facilities.

Many narrow-gauge lines were employed for short-term tunnelling contracts. Most of these are unrecorded, so this list represents only a few of the many such lines.
