Mineral railway transport vehicles. Compact in size to accommodate narrow tunnel conditions underground. Includes freight cars, passenger cars, material cars, etc.

Miner cars are narrow-gauge railway vehicles used for transporting loose materials such as coal, ore, and waste rock in mines, typically requiring locomotives or winches for propulsion. Miner cars are categorized into five main types based on their structure and unloading methods: fixed miner cars (material cars, flat cars), dump trucks, single-side curved track side-discharge miner cars, bottom (side) discharge miner cars, and shuttle miner cars.
