Have you seen the screen saver of the colorful monorail cars from Busan Korean?

Located in Haeundae Blueline Park, this pastel-colored Sky Capsule monorail offers a leisurely 30-minute journey along the coastline, panoramic views of the ocean, and surrounding landscapes in a  private, elevated journey. It only opened in 2020

The Haeundae Sky Capsule runs 7-10m up aboveground and travels along a 2km section of the park. There are 80 sky capsules in operation and each capsule accommodates 4 at a time.
