Rail transport has long been the undisputed leader in terms of passenger and cargo transportation, but about a hundred years ago, it began to be replaced by cars and airplanes. Now trains have taken the lead again, due to significant increases in speed and coverage area, people are more likely to give them preferences a means of getting from A to B. In addition, the growth of mega-cities has made railways absolutely indispensable for commuting suburban residents. Besides, trains have become much safer as they are controlled by a supercomputer that has reliable protection against cyber attacks and covers the entire rail network. Trains are propelled by alternative energy sources and an electromagnetic field.
