A train serves as a primary means of transportation that combines numerous vehicles connected together along rail tracks. This allows for efficient transport of cargo or passengers. The term "train" originates from the Old French word "traîner," which itself stems from the Latin phrase "trahere," meaning to pull or draw.[1]\n\nThe locomotive powers a train, which may be a separate entity or embedded within individual vehicles equipped with motors in a self-propelled multiple unit configuration. Traditionally, steam engines held dominance; however, diesel and electric locomotives have become the most prevalent options, the latter drawing energy from overhead wires or supplementary rails. Trains can also be hauled by horses, propelled by an engine or driven by cable or water winches, use gravity on downhill slopes, or run on pneumatics, gas turbines, or battery power.\n\nTrain tracks consist primarily of two main rails with additional supplemental tracks including electric conducting rails and rack rails often used. Monorails and magnetic levitation guideways serve as alternatives occasionally employed in certain cases.[2]\n\nA passenger train consists of vehicles designed for transporting passengers and may feature impressive length and speed capabilities. The high-speed rail category stands out particularly due to its significant growth in long-distance operations. Advances in maglev technology aim to reach extraordinary speeds exceeding 500 km/h (310 mph). Some use the term light rail interchangeably with modern tram systems, although it may signify an intermediate classification positioned between a tram and train, mirroring characteristics seen in heavy rail rapid transit systems. Ultimately, the separation between a tramway and railway remains well-defined by laws within various nations.
