Why are trains more energy 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.

Due to its ability to move major quantities of freight at one time, rail shipping has a lower cost-per-ton-mile (the cost of moving one ton of freight one mile) than truck shipping. In fact, a train requires less energy to move from Point A to Point B and can carry the freight equivalent of 300 trucks.

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 ...

It is very true that when moving on flat ground in a straight line, trains on steel wheels and rails are the most efficient form of transportation. Rolling on steel rails reduces rolling resistance and traveling at slow speeds (compared to jet aircraft) reduced the force of air resistance.

Speed: Advantage to Trucking When comparing the speed of rail vs trucking shipping, the advantage goes to trucking. Extensive highways allow trucks to (usually) follow a shorter path between two points and deliver their cargo faster. Trucks are also generally easier to load and unload.

Biodiesel & Renewable Fuels: Traditionally, locomotives have run on petroleum diesel fuel, but railroads are now using renewable diesel and biodiesel blends to power them.

As a result, rail transport has many advantages such as high carrying capacity, economy, reliability, environmental impact, safety and independence from traffic congestion. It is a preferred method of transport, especially when large volumes and long-distance cargoes are to be transported.

While the US was a passenger train pioneer in the 19th century, after WWII, railways began to decline. The auto industry was booming, and Americans bought cars and houses in suburbs without rail connections. Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail.

It's important to understand the reasoning behind stopping before a railroad track. The biggest, most important reason is this: safety. Especially for large vehicles carrying passengers or dangerous materials, this is even more important. Trains are heavier and harder to stop than even a fully loaded semi truck.
