Trains both were and are very efficient means of transportation, both for freight and passengers. However following WW2 the car companies and the oil companies decided to shut down all existing commuter trains to increase their profits, they bought up the lines and either switched them to diesel buses or simply shut them down and selling the steel rails as scrap. Later these same companies lobbied Congress to subsidize highways and the airlines, stealing much long distance business from the railroads.
Without the funds to maintain the rails properly speeds had to be reduced, making trains look even less attractive to potential customers.
Even though trains had been around awhile, they could not run efficiently on poor quality tracks. Their tracks were too brittle.
Trucks were invented to make up for the inability of trains to transport materials where there were no train tracks. Trains were limited where trucks were not. Trucks were able to take goods anywhere without being limited to a track.
There are a step in the right direction to being energy efficient. Although some adjustments are still being made.
The first cars started being invented because people were complaining that horse drawn carriages and horse just weren't taking them places fast enough and trains were to expensive for normal transportation.
trains have improved by being a solid unlike they wasn't in the 1900
1) Maglev is a much better way to move people and freight than by existing modes. It is cheaper, faster, not congested, and has a much longer service life2)Maglev is very energy efficient. Unlike autos, trucks, and airplanes, Maglev does not burn oil, but instead consumes electricity, which can be produced by coal-fired, nuclear, hydro, fusion, wind, or solar power plants (the most efficient source now being nuclear).
The wagon trains were to form a circle when they were being attacked.
Efficient
Yes, trains are still being used today in large quantities.
I will choose both because effectivness and efficiency are important to the organization . I will choose the both because efficiency and effectivness are important to the organization.

Some do, some don't. In Europe at least, an increasing number of long distance trains have an electricity socket. Local trains are unlikely to have an socket. These are being added as trains are re-furbished, or in new trains, often in first class only as an incentive to travellers to choose first class.
