For a large Diesel Locomotive, the power involved near about 4,500 HP makes a Gearbox impractical. So these big machines are driven by electric motors both, AC and DC, driving each wheel. The engine drives an Alternator. The Torque/Speed Characteristics are matched by solid state power electronics. The right amount of

locomotive, any of various self-propelled vehicles used for hauling railroad cars on tracks. Although motive power for a train-set can be incorporated into a car that also has passenger, baggage, or freight accommodations, it most often is provided by a separate unit, the locomotive, which includes the machinery to generate (or, in the case of an electric
Locomotive - Diesel, Traction, Engines: By the end of the 1960s, diesel had almost completely superseded steam as the standard railroad motive power on nonelectrified lines around the world. The change came first and most quickly in North America, where, during the 25 years 1935–60 (and especially in the period 1951–60), railroads in the United
BATTERY-ELECTRIC LOCOMOTIVE TECHNOLOGY. Wabtec is leading the transition to low-carbon rail operations with FLXdrive — the world''s first 100% battery-electric, heavy-haul locomotive. The FLXdrive battery
As part of the contract worth €3.5 billion won in 2015, the company will be supplying 800 fully electric high-powered double-section locomotives of 12,000 HP (9 MW) for freight service, capable of hauling ~6,000 tonnes at a top speed of 120 km/hr. This is the largest Foreign Direct Investment project in the Indian Railway sector.
Definition and Function. Diesel electric locomotives are designed to be versatile machines capable of pulling both freight and passenger trains. They work by using a diesel engine to generate electricity which is then used to power electric motors connected to the train''s wheels through a transmission.
Modern locomotives can have 3000-6600 HP in just one engine. Major manufacturers of diesel locomotives include: EMD (Electro Motive Division) (part of GM), General Electric and at one time American Locomotive Company (ALCO). The collapse of ALCO happened as a result of business problems, General Motors and General Electric were able to
The diesel locomotive works on the diesel. 02. Powered by. The engine of the electric train requires electricity through overhead lines. The engine of the diesel train does not require direct power or electricity from overhead lines. 03. Power Generation. This type of locomotive does not generate the own power.
More Information. Electric Traction. Train Equipment. Electric Traction Control. Rolling Stock. Modern traction motor type using three phase AC electrical supply and now the favoured design for modern train traction systems. It can be used on DC and AC electrified railways with suitable control electronics and on diesel-electric locomotives.
Fig 1: The diesel-electric locomotive is self-contained, fairly efficient, widely used source of railroad motive power. (Image source: Springer International Publishing) Fig 2: This high-level block diagram of the diesel-electric locomotive shows that it requires a diesel engine, alternator (generator), and electric motors, plus their
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.
But locomotive builders and railroads, following the lead of carmakers and truck manufacturers, are turning to batteries big enough to power small towns as a way to curb carbon and diesel
The electrical system of an ALCO locomotive is a complex network that converts the diesel engine''s mechanical energy into electrical energy, which is then used to power the locomotive. The main generator, working in tandem with the traction motors, forms the heart of electric traction, while the control system ensures the correct amount
Locomotive July 7, 2023 admin. The power behind locomotives has been revolutionized by electrical components, enhancing their capacity, control, and efficiency. These locomotive parts and components form an intricate system that is responsible for locomotive operations. The traction motors convert electrical energy into mechanical
This Metra EMD F40PHM-2 locomotive uses a diesel–electric transmission designed by Electro-Motive Diesel. A diesel–electric transmission, or diesel–electric powertrain, is a transmission system for vehicles powered by diesel engines in
11 October 2017. First run. 19 May 2020. 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 model name stands for wide gauge (W), alternating current (A), goods traffic (G) locomotive-12. They entered trial service in
It might be surprising to know that in electric trains, the power collected from the overheadlines ends up in the grounding cable of the track after flowing It might be surprising to know that
In conclusion, the future of diesel locomotives looks bright with the development of hybrid and electric, improved engine efficiency and performance, and alternative fuel sources. As technology advances, we can expect to see more efficient and environmentally friendly diesel locomotives on the rails.
While Siemens is credited with introducing electric locomotion at an exhibition in Berlin, Germany during 1879 the electric motor has a history tracing back much further than one might think. In
Types of Locomotives Engines on Railroads. There are three primary types of locomotive engines: steam, electric, and diesel. Each possesses its own distinct method of generating the necessary power to transport substantial cargo over extensive distances. Let''s take a closer look:
Sixteen preserved, remainder scrapped. The Pennsylvania Railroad GG1 is a class of streamlined electric locomotives built for the Pennsylvania Railroad (PRR), in the northeastern United States. The class was known for its striking art deco shell, its ability to pull trains at up to 100 mph, and its long operating career of almost 50 years.
A typical freight rail locomotive in the US weighs more than 400,000 pounds and is powered by a 12-cylinder diesel engine that delivers over 4,000 hp. It''s over 75 feet long and stores over 4,500 gallons of fuel. Starting out from a dead stop the engine typically delivers a tractive effort of 200,000 lbs. to get moving.
Wabtec is a technology leader in electronic braking and positive train control, delivering railroads safety, productivity and efficiency improvements. Skilled Wabtec technicians provide everything from routine maintenance and repair services to complete locomotive rebuilds, upgrades and overhauls. We build new commuter and low-horsepower, low
Length. The length of a train engine can vary greatly depending on the type of engine and its intended use. For example, a diesel-electric engine used for freight trains can be up to 80 feet long, while a passenger train engine may be closer to 50 feet in length. The length of a is important because it impacts the number of cars it can pull and
In diesel and electric locomotives, the power generated by the engines or electric motors is transmitted to the wheels through a complex system of gears, shafts, and axles. The power is typically transferred to the wheels via a transmission system, which may include gearboxes, driveshafts, and differentials.
In this video, we discuss how a diesel-electric locomotive gets power from the engine to the wheels. We also discuss a very special feature diesel-electric l
The simplest version of an electric train is shown in fig 1a. Here, a single sliding wire collects electric power from the overhead lines. This power is fed to a single-phase induction motor. The induction motor''s rotor is connected with the wheels. To complete circuit, the induction motor''s other terminal is grounded.
