Bangladesh Railway Class 3000 is a class of meter-gauge diesel-electric locomotives operated by Bangladesh Railway. This is the latest and most modern meter gauge locomotive class of the Bangladesh Railway. These locos could be used on broad gauge track also by changing bogies.
In the 1960s, some shunting locos entered the fleet of the then Eastern Bengal Railway as class/series-number 3000. The number of these locos were 11 probably. [1] At present, none of them are active. None of them were preserved.
In 2020, 10 [2] locos produced by Hyundai Rotem of South Korea under the license of Electro-Motive Diesel (EMD) of USA, entered the fleet of Bangladesh. They were also given the 3000 series. Though in the first phase, 10 locos came, 20 more in the second phase [3] [4] and 70 more in the third phase [5] are planned to come in Bangladesh. The newer locos are used for both passenger and freight trains.
The newer locos use the EMD 8-710G3A-T2 as prime mover. Their power is 2,200 hp and can achieve speed up to 110 km/h. The wheel arrangement is Bo1-1Bo (Each bogie having 2 powered axles & 1 unpowered inner axle) having total of 6 axles but only 4 traction motors. There are controversy regarding the model of Alternator used in the first 10 locomotives of the series, as Hyundai Rotem provided TA9-12CA9SE instead of TA12-CA9, which was to be provided as mentioned in the contract. [6]
The number-series/class of these locos is 3000. New locos are numbered from 3001 to 3010. First Shipment of the second phase 3011-3020 is also arrived in Bangladesh recently and under trial. Unlike 3001-3010 this 10 has Air Conditioned cab. The class-name/specification of new locos is "MEI-20". Here, M = Meter-gauge, E = Diesel-electric, I = Hyundai Rotem and 20 = 22 × 100 = 2,000 hp (actually 2,200 hp). The class-name of old locos is unknown.
Hyundai Rotem (Korean: 현대로템) is a South Korean company that manufactures rolling stock, defense products and plant equipment. It is a part of the Hyundai Motor Group. Its name was changed from Rotem to Hyundai Rotem in December 2007 to reflect the parent company. It is also called Hyundai Railroad Technology Systems.
A road switcher is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere.
The EMD DDM45 is a meter-gauge diesel-electric locomotive built by EMD. The DD in the name means that it has eight axles in two trucks, giving it a D-D wheel arrangement, while the M stands for the meter-gauge track it was to operate on, and the 45 represents the EMD SD45 that the engine was derived from. They were built for service on the Estrada de Ferro Vitória a Minas (EFVM) in Brazil. In the early 1970s, the EFVM needed not only to expand its locomotive roster, but to use the most powerful single-engined locomotives available, and the SD45 represented the highest-rated model that EMD had to offer at the time.
The Indian Railways primarily operates a fleet of electric and diesel locomotives, along with several compressed natural gas (CNG) locomotives. Steam locomotives are operated on a few World Heritage Sites and also run occasionally as heritage trains. A locomotive is also known as a loco or more popularly as an engine. The country's first steam locomotive ran on the Red Hill Railway from Red Hills to the Chintadripet bridge in Madras in 1837.
Co-Co is the wheel arrangement for diesel and electric locomotives with two six-wheeled bogies with all axles powered, with a separate traction motor per axle. The equivalent UIC classification (Europe) for this arrangement is Co′Co′, or C-C for AAR.
The EMD GP49 is a 4-axle diesel locomotive built by General Motors Electro-Motive Division. Power was provided by an EMD 645F3B 12-cylinder engine which generated 2,800 horsepower (2.09 MW). The GP49 was marketed as one of four models in the 50 series introduced in 1979. The 50 series includes GP/SD49 and GP/SD50. Both the GP and SD50 were relatively popular with a total of 278 GP50s and 427 SD50s built. The SD49 was advertised but never built and a total of nine GP49s were built.
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 G Class are a class of diesel locomotive built by Clyde Engineering, Rosewater and Somerton for V/Line between 1984 and 1989.
The Stadler Euro is a class of diesel-electric locomotives built by Stadler Rail for the European market. It is available in two basic variants, the four-axle Euro 3000, and the six-axle Euro 4000. These locomotives are powered by EMD 710 prime movers. A six-axle electric-only variant is marketed as Euro 6000; it is also built for the Iberian gauge.
Bangladesh Railway Class 2900 is, as of 2023, the most frequently used meter-gauge diesel electric locomotive of Bangladesh Railway along with Class 3000. This reliable locomotive series has been in service since 1999. Bangladesh Railway has a total 39 locomotives of this class. These 39 locomotives are being used in both passenger and freight services.
Bangladesh Railway Class 2600 is one of the most frequently used meter-gauge diesel electric locomotive classes of Bangladesh Railway. It is considered one of the strongest and most reliable locomotive classes among the fleet of Bangladesh Railway. These locomotives have been in service since 1988. Currently, Bangladesh Railway has a total of 16 locomotives of this class. These 16 locomotives are being used in both passenger services and freight services. All of them are in good condition.
Bangladesh Railway Class 2000 is the earliest meter-gauge diesel electric locomotive class of Bangladesh Railway. These locomotives have been in service since 1953 which make them the oldest running locomotives in the history of Bangladesh Railway. A total of 40 locomotives of this class were imported. After providing service for a long periods of time most of these locomotives are no longer in service. Only the serial number 2025 loco is active now.
In the rail transport system of Bangladesh, diesel locomotives are used by Bangladesh Railway. Among diesel locos, there are diesel-electric and diesel-hydraulic locos. Besides diesel locos, steam locos were used in the past, but now they are no longer used. By gauge, there are narrow-gauge (762 mm), meter-gauge (1,000 mm) and broad-gauge (1,676 mm) locos in Bangladesh. Among them, as no narrow-gauge railroads are active, so the narrow-gauge locos are not used anymore.
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 British Rail Class 69 is a class of diesel locomotives which are converted from Class 56 locomotives. The conversion work is performed by Progress Rail at their workshop in Longport.
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.
The Indian locomotive class YDM-5 is a class of diesel-electric locomotive that was developed in 1964 by General Motors (GM-EMD) for Indian Railways. The model name stands for Metre gauge (Y), Diesel (D), Mixed traffic (M) engine, 5th generation (5). They entered service in 1964. A total of 25 YDM-5 locomotives was built between 1963 and 1964.
The Indian locomotive class YDM-3 is a class of diesel-electric locomotive that was developed in 1964 by GM-EMD for Indian Railways. The model name stands for Metre gauge (Y), Diesel (D), Mixed traffic (M) engine, 3rd generation (3). They entered service in 1962. A total of 30 YDM-3 locomotives was built between 1961 and 1962.
The WDM-2G is a class of diesel electric genset locomotive used in Indian Railways. It is one of the rarest locomotives in India with only two units being produced by Patiala Locomotive Works (PLW). The locomotives were produced with an intention of being fuel efficient and to be used for light to medium duties such as short passenger runs along with occasional shunting. They are one of the only two classes of locomotives in India to feature multiple prime movers, the other example being WDS-6G, which was designed solely for shunting. They have a rated power of 2,400 HP.
