The Indian locomotive class WDG-4 is a type of six-axle (Co-Co) freight-hauling diesel-electric locomotive with AC electric transmission designed by General Motors Electro-Motive Diesel in 1997–1998 for Indian Railways, where they are classed as WDG-4. Derived from the EMD SD70MAC, it is powered by a 4,000 hp (3,000 kW) 16-cylinder EMD 710G3B prime mover. Thirteen were built by EMD as order #958647, and a further eight were exported in kit form and assembled in India. The class entered service in 1999. A Dedicated Passenger version of this locomotive, the WDP-4, has also been produced, with a Bo1-1Bo Wheel Configuration, which entered service in 2001. These locomotives are also famous for, and can be identified, by the distinct and unique Jet Plane-like sounding capability of the EMD 710 prime mover.
The Indian locomotive class WDP-4 is a passenger-hauling diesel-electric locomotive with AC electric transmission designed by General Motors Electro-Motive Division and built by both GM-EMD and under license by Banaras Locomotive Works (BLW) of Varanasi, India for Indian Railways as the classes WDP4, WDP4B and WDP4D. The GT46PAC is a passenger version of the previous Indian Railways EMD GT46MAC freight locomotive. The locomotive has a 16-cylinder 710G3B diesel engine and is one of the fastest diesel-electric locomotives in service in Indian Railways.
The ALCO DL560C is a series of diesel-electric locomotive with AC electric transmission designed by the American Locomotive Company and produced under license by Banaras Locomotive Works (BLW) Varanasi, India for Indian Railways as their classes WDM-2, WDM-3A/2C, WDM-3D and WDG-3A for operation in India. The locomotive is fitted with a 16-cylinder ALCO 251 B, C diesel engine. In the early 1960s Indian Railways needed a reliable diesel workhorse to gradually replace its steam locomotive fleet. Equal numbers of ALCO's DL560C and EMD's G16 were chosen for trials. More locomotives of each of these were purchased for more trials. Indian Railways was keen on producing these locomotives in the country rather than depending on imports. EMD did not agree for a Transfer-of-Technology, while ALCO did. Thus ALCO DL560C was chosen for the job due to its easy maintenance, reliability and simple operation. And from then on vast numbers of this loco in different configurations have been produced and remain the main diesel traction power of Indian Railways.
The Indian locomotive class WAG-12B is a class of 25 kV AC electric locomotives that was developed in 2017 by Alstom with technological collaboration with Indian Railways.

The Indian locomotive class WDG-4G is a class of dual-cabin freight-hauling diesel-electric locomotive used by the Indian Railways (IR). The locomotive is designed by GE Transportation and is based on its Evolution Series, which are used in North America. The class is meant for freight hauling and replaces the older American Locomotive Company (ALCO)-designed locomotives, which have been the mainstay diesels of Indian Railways since 1962. Equipped with a 12-cylinder fully turbocharged GEVO engine, it is claimed to be 50% more environmentally friendly than its predecessors and is the first in the country to be compliant with level one of the emission norms set by the International Union of Railways (UIC-1). The locomotive has two cabs for easy reversal, both of which are air conditioned.

The model name stands for broad gauge (W), Diesel (D), Passenger traffic (P) engine, 1st generation (1). They entered service in 1995. A total of 69 WDP-1 units were built at Banaras Locomotive Works (BLW), Varanasi between 1995 and 1999.
The Indian locomotive class WDG-3A is a class of diesel-electric locomotive that was developed in 1994 by Banaras Locomotive Works (BLW),Varanasi for Indian Railways. The model name stands for broad-gauge (W), Diesel (D), Goods traffic (G) engine, 3,100 hp (3A) locomotive. They entered service on 18 July 1995. A total of 1,164 WDG-3A units were built between 1994 and 2015 at BLW, Varanasi with a few units being produced by Diesel Loco Modernisation Works (DLMW) and Parel Workshop.
The Indian locomotive class WDG-6G is a class of diesel-electric locomotive used by the Indian Railways for freight duty. The locomotive is a higher power variant of the WDG-4G locomotive which was also designed by General Electric. The design platform is based on the GE Evolution Series and features a 4-stroke 16-cylinder fully turbocharged engine which delivers around 6,000 horsepower, making it the most powerful diesel locomotive of IR. It is the only 6,000 HP Diesel electric locomotive at 23t/axle weight, making it the lightest locomotive in its category in the world.
The Indian locomotive class WAG-11 is a class of twin-section 25 kV AC electric locomotives that was developed in 2018 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. This freight engine has been designed for a speed of 105 km/h and weighs 252 tons. It is equipped with a three-phase induction motor, four power converters and regenerative as well as pneumatic braking system. The model name stands for broad gauge (W), Alternating Current (A), Goods traffic (G), and 11th in series (11). They entered trials service in 2019. A total of 4 WAG-11 pairs have been built by Banaras Locomotive Works (BLW), Varanasi.
The Indian locomotive class WDG-5 is a class of heavy haul Diesel-electric locomotive built by Banaras Locomotive Works, Varanasi in collaboration with Electro-Motive Diesel. At a rated power output of 5,500 horsepower (4,100 kW), it is the second most powerful diesel locomotive class on Indian Railways, just out-powered by the 6,000 horsepower (4,500 kW) WDG-6G. Derived from the EMD SD80MAC, it was meant as a direct upgrade to the WDG-4 aka GT46MAC. The locomotive series is named Bheem, after the strong Pandav brother from epic Mahabharata. The loco has the 2-stroke Turbocharged EMD 20-710G3B-ES of the EMD SD80MAC and an AC-AC transmission. Since the loco has been developed by installing a v20-710 prime mover and replacing the standard v16 in the WDG4 GT46MAC locomotive, the model was re-designated by adding 4 to the predecessor model, with GT-46 becoming GT-50, owing to the number of cylinders going from 16 to 20, thereby making it the First EMD locomotive in the GT-series to use a v20-710 engine.
