List of electric locomotives of India
This is a list of all electric locomotives that have been or are being operated by Indian Railways.
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 3,100 hp (2,300 kW) locomotive, and a WDM-3F is 3,600 hp (2,700 kW).
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.
Syntax
- First letter (gauge):
- W – Broad gauge (wide) – 5 ft 6 in (1,676 mm)
- Y – Metre gauge (yard) – 1,000 mm (3 ft 3 3⁄8 in)
- Z – 2 ft 6 in (762 mm) narrow gauge
- N – 2 ft (610 mm) narrow (toy) gauge
- Second letter (motive power):
- D – Diesel
- C – DC electric (DC overhead line)
- A – AC electric (AC overhead line)
- CA – DC and AC (AC or DC overhead line); CA is considered one letter
- B – Battery (rare)
- Third letter (job type):
In WCM-4, W denotes broad gauge; C denotes DC Electric power; M denotes mixed use (goods and passenger service), and 4 denotes fourth Generation. In WAP 5, W is broad gauge; A is AC electric; P is passenger service, and 5 indicates that the locomotive is the fifth model used.
Broad-gauge locomotives
Broad-gauge electric classification codes are:
- WAM – Wide AC electric mixed
- WAP – Wide AC electric passenger
- WAG – Wide AC electric goods
- WCM – Wide DC electric mixed
- WCP – Wide DC electric passenger
- WCG – Wide DC electric goods
- WCAM – Wide AC/DC electric mixed
- WCAG – Wide AC/DC electric goods
