Classification

Locomotives were classified by track gauge, motive power, function and power (or model number) in a four- or five-letter code. The first letter denotes the track gauge. The second letter denotes motive power (diesel or electric), and the third letter denotes use (goods, passenger, mixed or shunting). The fourth letter denotes a locomotive's chronological model number. In 2002, a new classification system was adopted. For newer diesel locomotives, the fourth letter denotes their horsepower range. Not all diesel locomotives were reclassified, and the fourth letter continues to denotes their model number. A locomotive may have a fifth letter, generally denoting a technical variant, subclass or subtype: a variation in the basic model or series, or a different motor or manufacturer. Under the new system, the fifth letter further refines horsepower in 100-hp increments: ''A'' for 100 hp, ''B'' for 200 hp, ''C'' for 300 hp and so on. A WDP-3A is a locomotive, and a WDM-3F is . The system does not apply to steam locomotives, which are no longer used on main lines. They retain their original class names, such as M- or WP-class.

Steam

Nineteenth-century railway companies ordered custom-built locomotives, usually from British manufacturers. The multiplicity of similar-but-not-identical designs increased manufacturing cost and slowed production. During the 1890s, many British manufacturers were recovering from work outages, thus Indian railway companies looked to Germany and the United States for locomotives. Engines used were: * Bengal Nagpur Railway: **Class F:
