How Much Does A Locomotive Weight And Cost?
A locomotive is a powerful and essential piece of equipment for any railroad, and its weight and cost are important factors to consider for any company or organization in the rail transport industry.
When it comes to weight, a typical locomotive weighs between 200 and 250 tons. However, the heaviest locomotive ever built is the Union Pacific Big Boy, which weighed in at an impressive 1.2 million pounds (600 tons).
The cost of a new locomotive can vary greatly depending on the type, size, and specifications. For example, a smaller, simpler locomotive may cost several million dollars, while a larger, more advanced locomotive with more features can cost tens of millions of dollars.
There are several factors that can affect the cost of a locomotive. The type and size of the locomotive, as well as the specifications and features included, can all have an impact. Additionally, the manufacturer of the locomotive can also affect the cost.
In addition to purchasing new locomotives, many railroads and companies choose to purchase used locomotives. These can be obtained from other railroads or leasing companies, and the cost will depend on the age, condition, and mileage of the locomotive.
Another option for companies and organizations in the rail transport industry is to lease a locomotive instead of purchasing it outright. This allows them to use the locomotive for a set period of time, and then return it or purchase it at the end of the lease term. Leasing a locomotive can be a more cost-effective option for some companies, particularly those that may not need a locomotive on a long-term basis.
Using a diesel engine instead of a gasoline engine makes a locomotive more efficient. There are many advantages of using a diesel engine over a gas engine, including its ability to provide more power for the same size and weight. However, these advantages aren’t the only reasons why a locomotive powered by a diesel engine is preferred.
GE Freight Locomotives Weigh Around 200 Tons
GE has a history of building innovative transportation products that help change the world. From a small papier mache globe exhibited at the 1900 World’s Fair in Paris to the largest electric locomotive in the world, GE has been a leader in transportation innovation.
In the company’s early days, GE began producing several electrical components. Then, in 1919, Herman Lemp developed a system for controlling a diesel-electric locomotive’s mechanical and electrical parts with a single lever. The resulting “GEVO” engine significantly reduced the number of parts and increased reliability.
A new generation of locomotives was built in the 1950s, including GE’s first gas-turbine-powered machines. These engines were designed to work in conjunction with common GE 752 traction motors. However, they proved less efficient than diesel-electric locomotives.
After the gas-engine program ended, GE engineers began working on a new design for a mainline diesel-electric locomotive. This was the Universal Line, a series of six models ranging in horsepower from 2,500 to 3,500. The designs were relatively simple and easy to maintain.
In the 1950s, GE’s rail heritage continued with the introduction of its U-Series, one of the largest locomotive builders in the world. The locomotives were low-slung machines that hauled hopper cars loaded with minerals. The units were manufactured at GE’s Erie Works in Erie, PA.
General Electric also built steeple-cab locomotives in Schenectady, NY. The steeple-cab design was heavier than typical steam locomotives. Four 360-hp direct-current electric motors powered it. The locomotives ran on a fixed overhead electrical distribution system. These locomotives were capable of accelerating at up to one mph per second with trains up to 800 tons.
Caterpillar Emd 710 Series Engine
Despite being a relatively recent development, the Electro-Motive 710 series engine is still used across a variety of industries. General Motors Diesel in London, Ontario manufactured the engine.
The 710 engine is a two-stroke, “V” shaped design. The engine has a displacement of 710 cubic inches. In addition, the engine has a centrifugal clutch, which allows the turbocharger to act as an exhaust-driven turbocharger at higher speeds. This allows for increased power output while reducing fuel consumption.
The Electro-Motive 710 is the latest in a line of two-stroke diesel engines, which have been produced since 1985. The engine is used in locomotives, which typically carry a switch-duty cycle. This type of locomotive has a fuel tank with a capacity of 5,500 gallons of diesel fuel. There are also up to 250 gallons of engine oil in the fuel tank.
In the early 1980s, the Electro-Motive Division was owned by General Motors. In the 1990s, General Motors leased the locomotive division to a subsidiary. The subsidiary, PSR, put the units in storage lines.
The Electro-Motive 710 engine was a result of reliability problems with the model 645F. However, the engine was also a step forward in EMD’s quest to develop high-horsepower AC traction diesel locomotives. Eventually, the engine was renamed the “H engine.”
The engine was used on early versions of the SD90MAC, which featured an isolated cab, advanced cooling, and computer microprocessor software. The engine was designed to produce 6,000 to 4,300 horsepower.
Diesel Engines Are More Efficient Than Gasoline Engines
Compared to gas engines, diesel is more efficient and produces more energy for less fuel. They can also be cheaper to fill.
Despite the efficiency advantage, the cost of owning a diesel vehicle is still higher than its gasoline counterpart. The upfront cost of buying and maintaining a diesel car can be prohibitive.
A diesel engine’s fuel efficiency depends on the compression ratio and the amount of air injected into the combustion chamber. High compression ratios lead to better thermal efficiency. The density of the fuel is also important.
Diesel fuel is a good deal denser than gasoline. The density of a gallon of diesel is about 13-18% more than a gallon of gasoline.
Diesel fuel is much less volatile than gasoline. This is because the fuel’s density and volume indicate the type of hydrocarbons that are contained within.
The compression-ignited injection system of a diesel engine is the secret to its efficiency. In addition, the cylinder walls of a diesel engine are thicker than those of a gas engine. This allows for greater oil movement. Consequently, diesel can achieve more torque at lower speeds.
A compression-ignited diesel engine can have a higher compression ratio than a gasoline engine. This increase in compression reduces the heat difference between the two types of fuel.
The EPA estimates that a modern 3.0-liter turbocharged diesel V6 engine can achieve a combined mpg rating of 25. This is nearly two miles per gallon more than a comparably-sized gas engine.
An Air-Powered Piston Provides Braking.
Several forms of air brakes have been adopted on railways worldwide. While some use hydraulic fluid, others do not. Nevertheless, the basic air brake is an efficient, fail-safe system that is widely adopted.
There are two major systems that are used on locomotives and freight wagons. The first system is a straight-air system. This consists of a pressurized air cylinder connected to a piston that applies service brakes. The piston must be adjusted to a specified length to achieve the correct travel.
The second system is a two-pipe system. This consists of a main reservoir pipe and a second pipe connected to the car reservoirs. The locomotive constantly pressurizes the main reservoir pipe. It also supplies air for other auxiliary systems. The main reservoir pressure is 860-970 kPa.
The two-pipe system is found on most passenger trains and freight wagons. The emergency section of the two-pipe system is equipped with a triple valve that contains an auxiliary vent port. This serves to vent the air from the brake pipe to the atmosphere and speed up the propagation of the emergency reduction rate.
The triple valve also features a mechanism that transfers air from the reservoir feed to the train line. The double-headed arrow refers to the fact that the air from the reservoir increases the air pressure in the brake cylinder. This is not possible with a single-pipe system.
During the modernization process of a locomotive, the assemblers remove the old engine and other worn-out parts. These are replaced with new components and updated control systems. These upgrades increase the life of the locomotive by seven to nine years. This process costs only about half of the price of a brand-new locomotive. This is why locomotive remanufacturing has become important to GE Transportation’s business strategy.
The remanufacturing process of a locomotive is based on specific technical specifications. The goal is to restore the cores of the locomotive to the same condition as the original. In addition, the remanufactured part is given the same warranty as the new part. This process also helps in improving the performance of the locomotive.
The process begins with the incoming machine being completely stripped. It is then washed. The crews then remove the cab, truck assemblies, and other parts. These parts are then sanded to the correct size. The exterior is also cleaned. Mechanical problems are then repaired.
The remanufactured locomotive parts are then distributed throughout the shop. These components are then qualified and given a certificate of conformity before being introduced into service. The remanufactured locomotive is then tested on a three-mile test track.
The remanufacturing activity occurs in the same general plant assembly area as assembling a new locomotive. The United States Environmental Protection Agency governs the process.
Train Length and Tonnage Have Increased Dramatically.
Increasing train length and tonnage have its advantages. Besides increasing overall capacity, it helps improve operational efficiency. In fact, railroads spend hundreds of millions of dollars per year to increase their rail yards’ capacity. By increasing the length of the sidings, trains are able to pass one another. In addition, technology has enabled radio-controlled distributed power. The aforementioned technologies are just a few of the many improvements being made by today’s railroads.
The quest to move more freight has prompted engineers to build larger machines. To wit, some Class I systems have been known to operate trains in excess of 12,000 feet. In some cases, a single train may have as many as 12,000 cars onboard. The good thing is that the crew costs for such a feat aren’t that much more expensive. In addition, a number of companies are proving that the quest to move more freight pays off with improved overall operational efficiency. In the grand scheme of things, there’s no question that a train of a typical length will carry more freight than a train of the same size but with fewer cars.
The most efficient and cost-effective way to achieve this is by deploying a few clever tactics. For example, a company might have a few short-duration intermodal trains tasked with hauling cargo to and from terminals. This isn’t a problem since some of these trains can be up to double the length of the average train. As a result, a railroad might be able to achieve a tally of six such trains in a day, compared to the five a week or more typical in the past.
