Indian Railways operates India''s railway system and comes under the purview of the Ministry of Railways of Government of India.As of 2023, it maintains over 108,706 km (67,547 mi) of tracks and operates over 13,000 trains daily with a fleet of 14,800 locomotives.The railways primarily operates a fleet of electric and diesel locomotives

Diesel-electric locomotives come in three varieties, according to the period in which they were designed. These three are: DC - DC (DC generator supplying DC traction motors);

Diesel locomotives are some of the coolest modes of transport out there. Giant machines like these are just full of technological treats. Explore a hybrid-diesel locomotive — from engine to engineer controls.

The difference between diesel and electric locomotives is that the diesel engine carries its own power plant, which is the diesel prime mover, instead of being connected from the overhead wires. Diesel-electric locomotives usually have two different types of electric current, AC and DC. AC current provides improved traction over DC locomotives.

Diesel Locomotive Works (DLW) in Varanasi manufactures diesel-electric locomotives and spare parts for Indian Railways. It was established in 1961 in collaboration with ALCO, USA. DLW produces several types of locomotives annually with capacities ranging from 3,100 to 5,500 horsepower intended for both passenger and freight service.

The American Locomotive Company (ALCO), based in Schenectady, New York, United States produced a wide range of diesel-electric locomotives from its opening in 1901 until it ceased manufacture in 1969. This is a list of ALCO locomotive classes.. For individually notable locomotives, please see List of locomotives.There are numerous

The diesel locomotive also carries its own fuel supply, but the diesel-engine output cannot be coupled directly to the wheels; instead, a mechanical, electric, or hydraulic transmission must be used. The electric locomotive is not self-sufficient; it picks up current from an overhead wire or a third rail beside the running rails.

The first generation of diesels is typified by small, low-horsepower locomotives compared to later eras. Streamlined (cab-unit) models were the norm until the early 1950s, when railroads realized the versatility of the road switcher. Road diesels were typically around 1,500 hp, with some passenger diesels (EMD Es and Alco PAs) at 2,000

In todays video, we look at how a diesel-hydraulic locomotive uses the incompressibility of fluid to transmit power from the engine to the wheels. We also ta

Read about the history of diesel locomotives, how they function and operate, and the dozens of different models built by the five major manufacturers.

The first commercial steam locomotive started running in 1812. This type of locomotive was in general use until 1950s when it fell out of favor and other types took over. Diesel locomotive has a diesel engine with internal

Diesel locomotives of British Rail. British Rail operated a large number of different diesel locomotive types. The majority of these were built between 1955 and 1968. Many classes were rushed into service as part of the 1955 Modernisation Plan, but poor reliability and a rapid decline in rail transport meant that some would have very short

Locomotive - Diesel, Electric, Hybrid: There are three broad classes of railroad equipment that use diesel engines as prime movers: 1. The light passenger railcar or rail bus (up to 200 horsepower), which usually is four-wheeled and has mechanical transmission. It may be designed to haul a light trailer car. Use of such vehicles is very limited. 2. The four-axle

The following is a list of locomotives produced by GE Transportation Systems, a subsidiary of Wabtec.All were/are built at Fort Worth, Texas or Erie, Pennsylvania, in the United States.Most (except the electrics, the switchers, the AC6000CW, and the Evolution series) are powered by various versions of GE''s own FDL diesel prime mover, based on a

Diesel electric locomotives are a type of locomotive that uses diesel engines to generate electricity, which then powers electric motors to move the train. These locomotives have been in use since the early 20th century and have undergone significant evolution over the years to become the efficient machines they are today.

The British Rail Class 56 is a type of diesel locomotive designed for heavy freight work. It is a Type 5 locomotive, with a Ruston-Paxman power unit developing 3,250 bhp (2,423 kW ), and has a Co-Co wheel arrangement. Enthusiasts nicknamed them "Gridirons" (or "Grids" for short), due to the grid-like horn cover on the locomotive''s cab

Although diesel locomotives first came to American railroads in the 1920s, their use was confined to switch engines, and later to passenger train locomotives. It wasn''t until 1940 that the Electro Motive Division of General Motors (EMD) demonstrated that diesels could practically replace steam locomotives in heavy-duty service. A pioneer freight diesel,

Diesel locomotives. The 1955 diesel locomotive classes are given in brackets where applicable.. A large number of different shunter types were purchased by British Rail and its predecessors, many of which were withdrawn prior to the introduction of TOPS.The tables below attempt to list the different types and the different classifications used to describe

Diesel-electric locomotives usually have two different types of electric current, AC and DC. AC current provides improved traction over DC

Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.

Most yard-switching and short-haul locomotives are equipped with diesel engines ranging from 600 to 1,800 horsepower; road units commonly have engines ranging from 2,000 to 4,000 horsepower. Most builders use V-type engines, although in-line types are used on smaller locomotives and for underfloor fitment on railcars and multiple-unit train-sets.

Locomotive - Steam, Diesel, Electric: Electric-traction systems can be broadly divided into those using alternating current and those using direct current. With direct current, the most popular line voltages for overhead wire supply systems have been 1,500 and 3,000. Third-rail systems are predominantly in the 600–750-volt range. The disadvantages of direct

The steam locomotive was a self-sufficient unit, carrying its own water supply for generating the steam and coal, oil, or wood for heating the boiler. The diesel locomotive also carries its own fuel supply, but the diesel-engine output cannot be coupled directly to the wheels; instead, a mechanical, electric, or hydraulic transmission must

Cab units are a type of diesel locomotive that sport a full length hood and cab on one end, streamlined into a seamless design. Electro-Motive first introduced this type in the mid-1930s and its models became affectionately known as "covered wagons." However, all of the major builders from that era offered their own version (except for
