The Indian locomotive class WDG-6G (GE ES57ACi) [1] 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 (4,500 kW), making it the most powerful diesel locomotive of IR (second-most being the WDG-5 aka EMD GT50AC). [2] 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.
Two units were produced by Wabtec's plant in Pennsylvania, United States, and delivered to India in 2019. [3] Initially, a few will be made in USA. Under the 'Make in India' initiative of Indian Government, GE will manufacture all remaining units at its factory in Marhowra, Bihar. GE has also built maintenance sheds at Roza in UP and Gandhidham in Gujarat.
The first two locomotives in the series, 69001 and 69002, were recently sent to South Central Railways' Maula Ali (MLY) Diesel Locomotive Shed. The locos underwent Confirmatory Oscillograph Car Run (COCR) trials on the Vikarabad – Parli section of South Central Railway [4] and were approved by Research Design and Standards Organisation for further field trials on the Dedicated Freight Corridor by Roza Locomotive Shed.

The Little Joe is a type of railroad electric locomotive built by General Electric. The locomotives had twelve axles, eight of them powered, in a 2-D+D-2 arrangement. They were originally intended to be exported to the Soviet Union and designed to operate on Soviet Railways (SZhD) 3,300-volt DC overhead line system. They were never exported to the Soviet Union due to rising political tensions. Only 20 were built, with 15 sold to domestic operators and five exported to Brazil.
The Evolution Series is a line of diesel locomotives built by GE Transportation Systems, initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The line is the direct successor to the GE Dash 9 Series. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.
The GE AC4400CW, sometimes referred as "AC44CW" is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is like the Dash 9-44CW, but features AC traction motors instead of DC, with a separate inverter per motor. In appearance, the AC4400CW is somewhat similar to GE's more powerful locomotive, the AC6000CW.
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.

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 Indian locomotive class WDM-3D is a class of diesel-electric locomotive that was developed in 2003 by Banaras Locomotive Works (BLW), Varanasi for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine with 3300 horsepower (3D). The engine is classified WDM-3D though it outputs only 3300 hp and not 3400 hp as the name should suggest. They entered service in 2003. A total of 590+ WDM-3D were built at Banaras Locomotive Works (BLW), Varanasi between 2003 and 2016.

It is equipped with 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 20N-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.
