Which train engine is faster diesel or electric?

Power plant capacity is far greater than any individual locomotive uses, so electric locomotives can have a higher power output than diesel locomotives and they can produce even higher short-term surge power for fast acceleration. Electric locomotives are ideal for commuter rail service with frequent stops.

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.

It all comes down to efficiency; electric motors are far more efficient than internal combustion engines when it comes to creating mechanical energy, and this is particularly relevant with trains.

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?

No, trains have no gears, since these are unfeasible. That's why their fuel (if any) is converted to electric energy and then used to run motors.

Electric locomotives are typically 20% less expensive than diesel locomotives. Maintenance costs can be 25 to 35 percent lower and operating costs can be up to 50%.

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.

Even taking typical peaking demands into account, electric energy is typically less expensive than diesel fuel. The comparable cost for the 150-mph locomotive- hauled electric train was just $2.61 per train mile as compared to $6.10 for the diesel.

Bullet Trains Are Coming to America. Too Bad Our Old Rail Lines Can't Handle Them. Only a measly 375 miles of U.S. track are equipped for 100+ mph speeds. U.S. rail tracks are typically too old to handle the speed of new train technology.

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.
