# How Much Horsepower Does A Diesel Locomotive Have?

A diesel locomotive has how many horsepower? The diesel engine of a locomotive is coupled to a DC or AC electric generator. In each case, roughly 3,200 horsepower is generated. This energy is converted into a large amount of current, around 4,700 amperes, by the generator.

## How much HP do train engines have?

Trains are currently one of the world’s most essential modes of transportation. Others are cargo trains, while others are high-speed passenger trains. Electrical trains are the most well-known and widely used. It can run on coal, gas, oil, hydropower, nuclear power, or any other source of electric energy. This type of train is particularly beneficial since it can use a variety of natural resources to generate electricity. Another benefit of the electric train is that it is extremely silent and produces no smoke or pollution.

A locomotive is a steam engine mounted on wheels that is used in some trains. This locomotive is the engine that propels the train forward. Others, on the other hand, have an electric traction motor in their propulsion system that performs the same function as a locomotive. In the early 1800s, Scottish inventor Robert Davidson created the first full-scale electric locomotive.

Watts are a SI (International System) unit used to quantify the power provided by a locomotive or traction engine to a train. It was given the name Watts in honor of James Watt, a pioneer of the steam engine. Another number for measuring power is horsepower (hp), which is commonly used to describe the output of electric motors and internal combustion engines. One horsepower equals 746 watts when converted between the two. As a result, multiply by 746 to convert horsepower to watts, and divide by 746 to convert watts to horsepower. The power ranges between 5000 and 7000 horsepower in most trains.

## What diesel locomotive the range of horsepower is?

The diesel engine in a dieselelectric locomotive powers either an electrical DC generator (generally less than 3,000 horsepower (2,200 kW) net for traction) or an electrical AC alternator-rectifier (generally 3,000 horsepower (2,200 kW) net or more for traction), whose output powers the locomotive’s traction motors. The diesel engine and the wheels are not mechanically connected.

The diesel engine (also known as the prime mover), the main generator/alternator-rectifier, traction motors (usually with four or six axles), and a control system consisting of the engine governor and electrical or electronic components such as switchgear, rectifiers, and other components that control or modify the electrical supply to the traction motors are all important components of dieselelectric propulsion. In the most basic example, the generator can be linked directly to the motors using only the most basic switchgear.

## How many miles per gallon does a diesel locomotive get?

The formula for our 2018 fuel economy rating is as follows: (Source: CSX R-1 Report 2018)

• Lines 1+3 (Line 4) of Schedule 750, Diesel Fuel Consumption (Freight + Switching) = 423,998,863 gallons

Over the previous decade, CSX has spent more than \$2.8 billion on improving locomotive fuel efficiency and lowering emissions.

The ton-mile-per-gallon is a unit of measurement used to compare the effectiveness of various types of transportation while moving freight.

The rail business keeps track of revenue ton-miles and publishes them “Surface Transportation Board Annual Report” (commonly referred to as the R1 Report). ‘The’ “The annual value of “Ton-Miles of Freight” is recorded in Schedule 755, line 110 of the R1 Report. In the R1 Report, Schedule 750, line 4, the rail sector also tracks and reports annual fuel usage. The system-wide train efficiency value is calculated using these two stated values.

For example, CSX recorded 208,712,027,000 ton-miles of freight in the R1 Report in 2018, and the combined line haul and switcher reported fuel usage was 423,998,863 gallons.

In other words, based on our 2018 revenue ton miles and fuel use, CSX trains can move a ton of freight nearly 500 miles on a gallon of fuel.

A freight truck’s fuel economy can be calculated in a similar method. For example, assuming an average 7 miles per gallon truck fuel efficiency and a typical truck payload of 19 tons, a heavy-duty diesel truck moving 19 tons of freight over 500 miles would burn approximately 71 gallons of diesel fuel. This freight haul’s efficiency would be computed as follows:

This efficiency could be described as follows: “On a gallon of gas, a truck can transport a ton of freight 134 miles.”

Similarly, a normal train might transport 3,000 tons of freight for 500 miles while using 3,049 gallons of diesel fuel. This freight haul’s efficiency would be computed as follows:

This efficiency could be described as follows: “On a gallon of fuel, a train can transport a ton of freight 492 miles.”

As illustrated by the ratio of 492 train ton-miles per gallon split by 134 truck ton-miles per gallon in this example, the train is nearly 3.7 times more efficient at moving freight.

## Why train engines are not turned off?

Because trains are so enormous and heavy, they require the highest possible brake line pressure to stop safely. Loco pilots never compromise on brake line pressure for obvious reasons. Another incentive to keep diesel train engines running is the engine itself. The diesel engine in a train is a huge machine with roughly 16 cylinders.

## How much diesel does it take to start a train engine?

Much depends on the size of the composition, because it varies depending on the weight of cargo added to the total weight of the composition (train), the type of engine power and speed, and the type of slope of the rail line he travels, which can reach 50 liters of diesel per kilometer, or hours worked.

## How many cars can 1 train engine pull?

What is the maximum number of train cars that an engine can pull? Depending on the track grade and other limits such as the length of passing loops, loading and discharging loops, and sidings, the number of wagons can range from 40 to 46. Each locomotive can draw 20 to 23 fully loaded carriages under normal operating conditions.

## How much is a locomotive worth?

Locomotives are massive machines that are incredibly strong and dependable. They come with a variety of features as well as electronic safety systems. However, the greater the price point, the more equipment there is.

So, what does a locomotive cost? A diesel locomotive can cost anywhere between \$500,000 and \$2 million. An electric locomotive, on the other hand, could cost more than \$6 million. The cost varies depending on whether it uses AC or DC traction, how much horsepower it has, and what electronics it contains.
