Are trains the most energy efficient?

Freight trains are several times more energy-efficient than trucks, because 1) the rolling resistance of the steel wheels of trains is lower than that of truck tires on the road, and 2) trains encounter less proportional wind resistance than trucks since a train car is partly shielded from the headwind by the car in ...

If you can't walk or cycle, then public transport is usually your best option. Trains are particularly low-carbon ways to travel. Taking a train instead of a car for medium-length distances would cut your emissions by around 80%. Using a train instead of a domestic flight would reduce your emissions by around 86%.

This chart shows average per-passenger fuel economy of various modes of travel. All forms of rail achieve relatively high values because of high ridership, proportionally low drag, and high electrification rates (electricity is inherently more efficient than combustion-engine propulsion).

One of the biggest environmental benefits of trains is that they consume far less energy than other types of transport. It takes a huge amount of fuel to get a plane carrying hundreds of people airborne, whereas trains are streamlined, require much less energy to move, and are increasingly able to run on electricity.

Today's train locomotives are already quite fuel efficient, especially compared to trucks. In fact, trains can haul one ton of goods an average of more than 480 miles on just a single gallon of fuel, making them 3-4 times more fuel efficient than trucks.

Trains measure in at 477 ton-miles per gallon of fuel, while for trucks it's only 145 ton-miles per gallon. [2,3] This is primarily because the rolling resistance of steel wheels on rails is less than that of rubber tires on the road. As a result, rail tends to be poorly suited for short trips.

Cars are also more efficient than public transportation. They can get you to your destination faster because they are not stopping at every station as a bus or train would. Also, with public transit, you often have to deal with delays. Your bus or train might be late due to traffic or other reasons beyond your control.

According to the 2021 U.S. Department of Energy Data Book, Amtrak is 46% more energy efficient than traveling by car and 34% more energy efficient than domestic air travel.

Rather, the term is more specific: A freight train can move one ton of weight about 450 miles on a single gallon of gas. To match this mileage, a one-ton car would have to get 450 mpg, and a two-ton vehicle would have to get 225 mpg. To car owners, this seems unbelievable. How can railroads do it?

Besides walking and biking, traveling by train remains one of the greenest and most environment-friendly options when getting around. Regardless if electric or diesel-powered, trains emit between 66 and 75 percent fewer carbon emissions when compared to cars and airplanes.
