Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches and transformers.
How is electricity being generated for electric locomotives?

By 1954, Olympic Games apparatus and events for both men and women had been standardized in modern format, and uniform grading structures (including a point system from 1 to 15) had been agreed upon. At this time, Soviet gymnasts astounded the world with highly disciplined and difficult performances, setting a precedent that continues. The new medium of television has helped publicize and initiate a modern age of gymnastics. Both men's and women's gymnastics now attract considerable international interest, and excellent gymnasts can be found on every continent. Nadia Comaneci received the first perfect score, at the 1976 Summer Olympics held in Montreal, Canada. She was coached in Romania by coach, (Hungarian ethnicity), Bela Karolyi. Comaneci scored four of her perfect tens on the uneven bars, two on the balance beam and one in the floor exercise. Even with Nadia's perfect scores, the Romanians lost the gold medal to the Soviet Union. Nevertheless, Comaneci became an Olympic icon.
Who set the first precedent that continues this day?
