Getting from the South Korean Capital of Seoul to the mountains of PyeongChang and 2018 Olympics is a long drive that takes more than 3 hours.
But engineers have now found a faster way, carving their way through one of the world's most mountainous regions and building 36 tunnels for bullet trains powered by 25-thousand volts of electricity.
These trains zip along at 200 miles an hour—cutting that 60 mile trip between Seoul and the ski areas of the Gangwon Provence to about an hour.
During the Olympics, 38,000 people a day are expected to travel on dozens of trains.
Even after the games end, the Governor of the Gangwon Province Choi Moon-soon says the $3.7 billion dollar bullet train will bring thousands of people a month to his region of South Korea.
"This is advantageous event for us in that regard, and we would like to promote Gangwon to the world," he said.
After the games, things will scale back but around 1,000 people a day are still expected to ride that bullet train. Officials hope it will be a big part of turning South Korea into a winter ski destination for this part of the world.
