Is electric train faster than diesel?

Some locomotives collect electricity from overhead cables, while others take power from a third “live” rail on the track. It is very expensive to build the lines or rails that carry the electric current, but electric locomotives are cleaner, quieter, faster, and more reliable than steam or diesel engines.

Electric Trains vs. Diesel-powered trains transfer about 30-35 percent of the energy generated by combustion to the wheels, while supplying electricity directly from an overhead powerline transfers about 95 percent of the energy to the wheels.

Every battery locomotive that replaces a diesel will reduce carbon dioxide emissions by 3,000 tons per year, Wabtec estimates. But it is unlikely they can quickly replace diesel-powered trains.

The train travels at 40 mph. In one hour, it will travel 40 miles and consume 310 gallons of diesel fuel between the three locomotives, or 7.75 gallons for every mile. That's about 0.13 miles per gallon, hardly 400 miles per gallon.

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?

Locomotives. Amtrak operates diesel, electric, and dual-mode (diesel or electric) locomotives.

The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles. The internal combustion engine was a dramatic improvement in efficiency over the steam locomotive, making substantial savings possible in maintenance and the elimination of widespread facilities.

Rail Tank Car Fun Facts Typically, tank cars have up to five times the capacity of truck, holding between 6,500 gallons to more than 31,000 gallons of liquid.

While the average car engine has about 200 horsepower, locomotive engines typically range from 2,000 to 4,500 horsepower. Train operators rely on diesel power across the full range of rail power applications.

Disadvantages of electric traction include: high capital costs that may be uneconomic on lightly trafficked routes, a relative lack of flexibility (since electric trains need third rails or overhead wires), and a vulnerability to power interruptions.
